How to Adjust Your 79 Series LandCruiser Handbrake: Step-by-Step Guide
Quick Answer: Adjusting the handbrake on a 79 Series LandCruiser involves three stages: loosening the cable at the lever, expanding the drum brake shoes via the adjuster accessible through the disc, and retightening the cable to remove slack. The correct lever travel is typically 4 to 7 clicks with firm engagement. A basic mechanical aptitude and two spanners are all you need.
The 79 Series LandCruiser uses a drum-in-disc rear brake setup, where a small drum handbrake sits inside the rear disc rotor. It's a robust and proven system, but like any mechanical component it needs periodic adjustment to keep the lever travel and holding force where they should be. A handbrake that pulls too high before engaging, or doesn't hold properly on a hill, is both a safety issue and a fail point at a roadworthy inspection.
This guide walks you through the full adjustment procedure for 79 Series models with factory disc brake rear assemblies, step by step.

Understanding the 79 Series Drum-in-Disc Handbrake
Before adjusting anything, it helps to understand how the system works. The 79 Series rear brake assembly combines a disc brake for normal braking with a small drum handbrake machined into the inside of the disc rotor. When you pull the handbrake lever inside the cabin, a cable pulls a lever arm on the backing plate, which expands a pair of small brake shoes against the inner drum surface of the disc.
There are two points of adjustment in the system:
- The shoe adjuster: Located inside the drum, accessed through a small hole in the disc. This sets the gap between the brake shoes and the drum surface. If this gap is too large, the cable has to pull the shoes a long way before they contact the drum, which means you'll have excessive lever travel inside the cab.
- The cable adjuster: Located at the handbrake lever inside the cabin. This removes slack from the cable after the shoe gap has been set correctly. It should always be adjusted second, after the drum adjustment is done.
Getting the sequence right, drum shoes first, cable second, is the key to a successful adjustment.
What You'll Need
- 10mm spanner or wrench (two of these is helpful)
- Flathead screwdriver
- Vehicle handbook or workshop manual (for the exact adjuster hole location on your specific build year)
- Jack stands or ramps if you need to access the underside comfortably (optional but recommended)
- Wheel chocks for safety
No specialist tools required. This is a straightforward DIY job for anyone with basic mechanical confidence.
Step-by-Step: How to Adjust the 79 Series Handbrake
Step 1: Loosen the Cable at the Lever
Start inside the cabin at the handbrake lever. Locate the cable adjuster, which is a 10mm nut with a locking nut on the same thread. Using two spanners, loosen both nuts to create slack in the cable. You want the cable completely loose at this point so that the shoes can settle to their natural resting position without any cable tension pulling them.
Do not try to adjust the cable without first going to the drum. Tightening the cable to compensate for worn or poorly set shoes is a shortcut that creates a false adjustment and will leave you with a handbrake that either drags or doesn't hold properly.
Step 2: Push Back the Rubber Stoppers
Move to the rear wheels. On the brake backing plate you'll find rubber bump stops, sometimes called stoppers, that limit how far the handbrake lever arm can travel. These prevent the lever arm from over-extending when the handbrake is released. Before you adjust the shoes, push these stoppers back away from the backing plate with your fingers or a flathead screwdriver to give the lever arm room to move freely during the adjustment process.
Step 3: Adjust the Drum Brake Shoes
This is the most important step. The drum adjuster is a star wheel mechanism accessible through a small hole in the face of the rear disc rotor. Rotate the disc until the hole lines up with the adjuster. You may need to consult your workshop manual or hold a torch to the hole to locate the star wheel on your specific model.
Use a flathead screwdriver to turn the star wheel adjuster. Turning it in one direction expands the shoes outward toward the drum surface; the other direction retracts them. Expand the shoes until there is light resistance when you rotate the disc by hand, then back off slightly until the disc rotates freely with only very light drag.
The goal is to have the shoes sitting as close to the drum surface as possible without actually dragging. Too much gap means excessive lever travel. Too little gap means the brake will drag at speed, which can cause vibration and premature shoe wear.
Repeat this process on the other rear wheel. Both sides should be adjusted to the same approximate feel.
Step 4: Reposition the Rubber Stoppers
With the drum shoes set correctly, reposition the rubber stoppers on both rear backing plates. They should sit approximately 1 to 2 millimetres away from the backing plate surface. This small clearance ensures the lever arm can fully release when the handbrake is off while still having its travel properly limited at full engagement.
Step 5: Adjust the Cable at the Lever
Return to the cabin and tighten the cable adjuster nuts at the handbrake lever. You are tightening these to remove the slack from the cable without adding pre-tension to the system. Pre-tension causes the brake shoes to drag when the lever is down.
Pull the handbrake lever up slowly and count the clicks. On a correctly adjusted 79 Series handbrake, you should feel firm engagement between 4 and 7 clicks of lever travel. If engagement is happening at 2 or 3 clicks, the cable is too tight. If you're pulling past 8 or 9 clicks before anything happens, the cable still has too much slack or the drum adjustment needs to come out further.
Step 6: Test and Verify
On a gentle hill, engage the handbrake at the 4 to 5 click position and release the foot brake. The vehicle should hold without creeping. If it holds, lower the lever fully and confirm the vehicle rolls freely with no brake drag.
Drive at low speed, then apply and release the handbrake lightly a few times to seat the shoes. Recheck the lever click count after this run-in. Some minor re-adjustment at the cable may be needed after the shoes have seated.
Common Problems and What They Mean
| Symptom | Likely Cause | Fix |
|---|---|---|
| Lever pulls very high before engaging (8+ clicks) | Shoes too far from drum, cable too loose | Adjust star wheel out, then retighten cable |
| Brake drags when lever is down | Cable too tight or shoes too close to drum | Back off cable adjuster, recheck drum clearance |
| Speed vibration or shudder after adjustment | Shoes over-adjusted and contacting drum while driving | Back off star wheel adjuster slightly on both sides |
| Uneven holding force left to right | One side adjusted more than the other | Re-adjust both sides to match feel and click count |
| Lever feels spongy with no firm stop | Rubber stoppers not repositioned, worn cable or shoes | Recheck stopper position, inspect shoes for wear |
When to Replace Rather Than Adjust
Adjustment has limits. If you find yourself re-adjusting the handbrake frequently, or if the lever travel stays long even after correct adjustment, it's worth inspecting the components rather than continuing to chase the adjustment.
Signs that replacement is needed rather than adjustment:
- Brake shoes worn below minimum thickness (visible when you access the adjuster hole)
- Glazed or scored drum surface inside the disc
- Frayed or stretched handbrake cable
- Cracked or collapsed rubber stoppers
- Handbrake lever arm pivot worn or binding
Handbrake components on the 79 Series are relatively straightforward to replace and are a worthwhile maintenance item for vehicles used in demanding conditions.

Upgrade Option: Dogbone Handbrake Brackets
Once your handbrake is correctly adjusted, there is one aftermarket upgrade worth considering if you want a firmer, more positive feel from the system. Aftermarket dogbone brackets (sometimes called donkey brackets) replace the factory handbrake lever return mechanism on the backing plate with a stiffer, more precisely toleranced alternative.
The factory setup can feel a little vague on older 79 Series, particularly on vehicles with high kilometres or after the rubber components have aged. A quality dogbone bracket firms up the lever arm pivot, reduces flex in the mechanism, and gives the handbrake a noticeably more positive engagement feel.
They are a straightforward fitment and a popular modification among 79 Series owners who do a lot of hill starts, off-camber parking, or towing. If the handbrake feel on your rig has always felt a little soft even when correctly adjusted, dogbone brackets are worth looking at as part of a broader brake service.

A Note on Safety
The handbrake is a safety-critical system. If at any point in the adjustment process you are not confident in the result, or if the handbrake does not hold the vehicle reliably after adjustment, do not drive the vehicle until the system has been inspected by a qualified mechanic. A handbrake that fails to hold on a hill is a serious risk to people and property.
This guide covers standard factory disc brake rear assemblies on the 79 Series. Vehicles that have been modified with different rear brake setups may require a different adjustment procedure.
Frequently Asked Questions
How many clicks should a 79 Series handbrake have?
A correctly adjusted 79 Series handbrake should engage firmly between 4 and 7 clicks of lever travel. Engagement below 3 clicks suggests the cable is too tight and the brake may drag. Engagement above 8 clicks suggests the cable is too loose, the drum shoes need to be expanded, or both.
Why is my 79 Series handbrake pulling too high?
High lever travel on a 79 Series handbrake is almost always caused by one of two things: the drum brake shoes being too far from the drum surface, or the cable being too loose. Start the adjustment at the drum star wheel adjuster to bring the shoes closer to the drum, then take up any remaining slack at the cable adjuster inside the cabin.
Can I adjust the 79 Series handbrake without removing the wheel?
Yes. The drum shoe adjuster is accessible through a small hole in the disc face, so wheel removal is not necessary for a standard cable and shoe adjustment. You may need to rotate the disc to align the hole with the adjuster star wheel.
What causes handbrake drag on the 79 Series?
Brake drag after adjustment is typically caused by the cable being too tight, the drum shoes adjusted too close to the drum surface, or the rubber stoppers not being repositioned correctly. It can also be caused by a seized cable or corroded lever arm pivot. Back off the cable adjuster first, then recheck the drum clearance.
How often should I adjust the 79 Series handbrake?
There is no fixed interval, but the handbrake should be checked any time lever travel feels excessive or the system fails to hold properly on a hill. Vehicles used for off-road driving or towing tend to need more frequent attention. A good habit is to check it during each tyre rotation or annual service.
What are dogbone brackets for the 79 Series handbrake?
Dogbone brackets are aftermarket replacements for the factory handbrake lever return mechanism on the rear backing plates. They provide a firmer, more precise lever arm pivot that reduces the vague or soft feeling some 79 Series owners experience from the factory setup, particularly on older or high-kilometre vehicles.
Will a handbrake adjustment affect my rear brakes?
Not if done correctly. The drum handbrake shoes operate independently of the rear disc brakes. Setting the shoe clearance correctly at the drum adjuster should not affect disc brake performance, provided you do not over-adjust the shoes to the point where they drag against the drum surface at all times.
Keep Your 79 Series in Top Condition
A correctly adjusted handbrake is a small job with a significant safety payoff. Done properly, it takes around 30 to 45 minutes, requires only basic tools, and leaves you with confidence that the vehicle will hold securely on any incline.
If you're spending time underneath your 79 Series for a handbrake service, it's also a good opportunity to inspect your brake lines, check the condition of your rubber stoppers, and assess whether any other undercarriage components need attention before your next trip.
