the rear is usually smaller and closer to the brake booster
The brake fluid reservoir in a 1991 Jeep Cherokee is located on the master cylinder. To add fluid, unscrew the cap and fill to the appropriate level with the appropriate brake fluid, more than likely dot 3.
It's on top of the transmission. Follow the tube coming from the master cylinder.
ABS was optional. Look for ABS wires that run alongside the normal brake lines, or look for the ABS pump assembly next to the brake master cylinder.
You buy a non abs booster and master cylinder, bolt them in, and bleed the system.
did you check your slave cylinder? is the hydraulic master cylinder leaking? did you try bleeding the clutch at all? what exactly does your pedal do? does it go straight to the floor or does it have pedal? there may be an air pocket in your lines? it could be alot of things you have to be more specific with your question
front front - rear rear.
You bleed the rear brakes the same way you bleed the front brakes. If you can't get brake fluid to come out the rear bleeders you may have a faulty master cylinder or the master was allowed to empty out the reservoir that feeds the rear and now it is air bound. Removing the master cylinder and bench bleeding the master may be what you need to do and don't let the reservoir go dry!
Failed Master Cylinder would be my guess. Replace the Master Cylinder.

The brakes and clutch share the same reservoir.
If the master cylinder reservoir is empty, you have a leak somewhere. If the master cylinder reservoir is full, the master cylinder is bad.
Do not pump the brakes. You will need to get all of the contaminated fluid out and refill the master cylinder.
Check your master cylinder, if it is still full or even partially full after you have tried the brake pedal several times, it's probably the master cylinder. if either side of cylinder reservoir is empty then you have a leak somewhere. Fill up the reservoir and pump the brakes several times and see if fluid is leaking. If fluid leaks at back of master cylinder then replace that. Also check the inside of the rear backing plates for evidence of wetness from a leaky wheel cylinder (rear drum brakes).
Sounds as though you still have air in the cylinders at rear.
The clutch gets its fluid from the master brake cylinder reservoir. The master clutch cylinder sits just below the master brake cylinder reservoir and is fed fluid by gravity.
To add brake fluid in a 1990 Mazda Protege, you need to locate the brake fluid reservoir and check the levels. The reservoir is located on the master cylinder for the brakes.
The ECU for the ABS brakes is attached to the Master cylinder for the brakes.
