Brakes - 1994 Isuzu Trooper

You need to install a brand new rear drum brake spring kit. Most likely. You have a broken brake shoe return spring it sounds like. That is if it is drum brakes.

Have your rear brakes inspected for excessive wear and to make sure the E-Brake Cable is not broken.

not sure what your asking here. front brakes are disc brakes and the rear are drum brakes and are hydraulic brakes that use dot 3 brake fluid. they should be power brakes as very few were sold as manual brakes.

bad brakes. (do explain tighter?) (to a blind, no leg man)
first fix bad brakes, then worry ABS. last
explain tighter.
in driving school , they teach , how to drive (safely) with a stalled engine
as the engine stalls. and vacuum hits zero, the booster slowly
dies and bingo , old fashion , manual brakes. (stalls are like that)
is that what is happening. engine stalls?, or the booster is failing?
what happens there is brakes are 100 ok, but just harder to press
the pedal so you press harder and brakes are ALL THERE.
the is all by DESIGN.. no accident (no pun)
see if you have any other bad brakes symptoms.
like these.

if brakes are 100% ok then , run the ABS scan or diagnostic
stated in the FSM , see what code you are getting.
then post that. ABS can not function correctly with bad brakes.

Certainly not. Still under warranty? Are they rear calipers or drum brakes with brake shoes? If drum brakes, they are self adjusting. You drive in reverse a short distance, hit the brakes, reverse again, hit the brakes. Every time you do that, the adjuster will move the brake shoes outward as needed to adjust for wear.
Try it and see if the brakes are better. Brakes with calipers and rotors do not require adjustment-they are truly self adjusting.

Generally speaking, the front brakes do most of the work of stopping--typically between 70-90%. The potential reasons for your truck's rear brakes wearing abnormally quickly include:

--the adjuster(s) on your rear drum brakes were adjusted too tight. (I'm pretty sure you have drum brakes in the rear.)

--You are doing a lot of heavy towing or hauling which is transferring more of the weight to the rear brakes. You'd have to be doing this often, though, and frequently meeting or exceeding the capacity of your vehicle to tow or haul.

--The proportioning valve, the master cylinder or a brake line somewhere is damaged, causing more hydraulic pressure than is correct to be applied to the rear brakes.

-- Your parking brake cable is kinked or damaged, causing the rear brakes to constantly rub. You'd likely smell burning brakes and notice heat from the wheels.

-- Your rear drum brakes are clogged up with brake dust and the springs cannot properly retract the brake shoes, resulting in constant rubbing.

Most likely one of these issues is your problem if you have premature rear brake wear.

drum brakes or disc brakes ? if drum brakes. yes but first remove the drums to be sure there is enough shoe left to adjust and to be sure there is no dirt or broken springs back there. if disc brakes no adjustment.

In my opinion You should check the brakes at least every year (or 100k miles), to be safe.

if you have rear drum brakes, check the rear brakes to see if you have any fluid leaks as in brake fluid from the wheel cylinder. it sounds like that is what is happening. when rear drum brakes get oil soaked they tend to lock up when the brakes are applied
