Symptoms
The handbrake won't hold the truck on a slope, or the lever comes up a long way before it bites.
The fix, step by step
- Unsealed 4X4 blames four things: poor adjustment, poor maintenance, worn 'dog bones' (the shoe struts) and the lever design.
- Check the lining on the small shoes inside the rear disc hats before you adjust anything.
- Adjust the shoes at the drum first, then the cable at the lever.
- Upgrades include longer dog bones for more shoe contact, and lever kits that move the pivot point to pull more cable.
- Unsealed admits no fix lasts forever, so chock the wheels on steep camp sites anyway.
