Need rear brake diagram for 1992 olds 88 royal ls

Question edited for clarity, spelling and typos.
Question moved to model category.

On a car that old it is the classic system, a pedal, a brake booster servo operated by vacuum with disc brakes on the front wheels and drum brakes on the rear wheels.

A hard pedal signifies a problem with the booster or a leak in the vacuum line.

Brakes acting like they are 'not releasing' is easy to check. Take the car for a run, to free them up. Put car into park, chock front wheels, jack up the rear and try and spin the wheels by hand. The should turn freely. Lower the back, chock the back wheels, put vehicle in neutral, jack up the front wheels and try and turn the front wheels by hand. They will be a little harder as you are also moving some gearbox parts.

Drum brakes can stick if the return springs break. Disc Brakes stick if incorrectly shimmed or the slider pins are seized with rust. They allow the caliper to float on either side of the disc rotor.

It's piggybacked on to the starter.

Also, check the neutral safety switch - Put your foot on the brake and put the car in neutral. Then try to start it. If it starts the neutral safety switch is bad. It could be the ignition switch. It could be to starter solenoid. Does it have an inertia switch? They rarely go bad but I have seen it.

I don't think a fuse diagram is what you need.
If you get under the dash and look up at the parking brake pedal assembly you might see a switch with one wire. Its a simple piece of metal that is a ground and it gets pushed off its contact by a nub on the brake mechanism. That switch may have come loose and is cust a constant ground or a plastic pin on the back of the switch which keeps it from turning could have broke off and it moved out of posistion.

you don't have to bleed the brakes if your just replacing pads,only time you have to bleed them is if you open system.











TIM.....

Open all bleeders
Pour brake fluid in the master cylinder
wait until all bleeders drip
Close right rear bleeder
Close left rear bleeder
Close right front bleeder

Its labled IGN, I belive # 16 or 18

Try turning the key to the on postion-not crank, just to he postion right before cranking. leave it in that postion for 15 min, Do this three and after the third time go ahead an try to start it. Hopefully this will reset your security for you.

Its on the fuel rail, mounted to the frame just in front of the rear wheel.

Best of luck.
