The handbrake does not work at the calipers. All cables are conected and working properly. The lever on th calipers moves freely but does not engage. The foot brakes works fine. Is there an adjustment somewhere on the caliper area?

Re: Handbrake problems with 1990 Isuzu Bighorn
Usually the adjustment is in the cables, either at the e-brake handle or at the caliper. I don't know of an adjustment on the caliper itself. Take a look at each rear caliper and see if it looks like something is broken off or missing. Something integral to the system may have just flat out broken off.
There is an adjustment on the calliper itself, there is a capping bolt i think its a 14mm from memory(dont quote me)once you undo that,(becareful not to round it off as it is thin in height) there is an allen key bolt on the inside that can be wound in or out depending on the adjustment, in yourcase obviously wind it in to be tighter, if this does not work its highly likely you calliper needs rebuilding sorry to say, i have issues with my handbrake also, due to its poor design i think it will always be very average

check the caliper fulcrum lever it sounds like it has siezed you may be able to free it off or you need a new one whichever always pump the brake pedal a few times before working handbrake otherwise the handbrake will be poor
yoiu dont touch the cable ,you remove the rear disks and adjust the shoes which are inside the the brake disk,check the type of system first though as it may have the handbrake on the caliper and if this type adjusting the cable will not work anyway as it will not pass the annual mechanical inspection on handbrake efficiency if the knife edge lever points are worn inside the caliper
slacken the handbrake cable under the centre consol so the cable is slack then it will just pop out ,if adjuster not their look under the floor behind the heat shroud ,sure its under the centre consol though on this motor think you have to pull the boot of the handbrake and its a ten mill nut with a long deep socket to undo it .Sorry old timers catches up with us in the end and i just do not remember
lets say the parking brake and handbrake are same operated by a mechanical lever or foot lever, ok. if the piston is threaded it has to be spun or threaded back in at the same time pressure is applied pushing it in, you may get away with doing it by hand with a pair of needle nose pliers spinning in and pushing at the same time, also you have have some success using a c clamp while sinning the piston in. keep in mind make sure the caliper has an integral handbrake/ park brake, cable is attached to caliper. hope this helps
Not 100% sure but peel back the handbrake lever cover.Beside the lever where the handbrake cable attaches there may be an adjuster there.Either directly on the cable itself or by locknuts threaded on the cable.Hope this helps
1. Raise the vehicle and release the handbrake. 2. De-adjust the handbrake cable.
Remove the locking pin.
Slacken the adjuster locknut.
Slacken the adjuster until the levers on the callipers have returned to their stops.
Paint alignment lines on the lever and caliper
4. Tighten the adjuster until the caliper levers move from the alignment
5. Apply the handbrake to equalise the cable.
6. Tighten the adjuster locknut to a minimum of three clicks and a maximum
of six clicks.
7. Fit a new adjuster locking pin.
8. Lower the vehicle.
The rear calipers work as the handbrake as well.
The solution is (with the engine running and in park/neutral) pump the brake pedal at the same time as pulling up and releasing the handbrake lever.You may have to do this quite a few times until the caliper resets its self.
You will notice the handbrake lever getting firmer as the calipers reset and adjust.
The handbrake adjuster is under the centre console behind the lever. If its coming too high, check that the levers at the rear brake calipers are free and moving back to their stop position - they are prone to seizing up on older or little used cars. They can usually be freed off with a bit of lube and working the lever back and forwards. If that dosn't work, unfortunately you'll need new calipers. Do not adjust the handbrake cable unless the caliper levers are at their stops as this seriously reduces handbrake efficiency!
