I'm new to this forum and Dodges in general. Every car I've owned up until now has been a Ford. I've tried searching but couldn't come up with anything.

I purchased this car...

...for $800, a 1987 Shelby Z. Along with a running (wrecked) turbo z parts car. This car will replace my '90 5.0 Mustang for daily driver duty.

The cars brakes were terrible. Whoever owned it before the guy I'd bought it from had not replaced the pads, and ran them so thin it could barely stop. Well it came with new pads in the back seat, and I was wondering if any of you could help me? I've only changed brake pads on Fords, and don't want to mess something up.

Thanks for the help.

Do not forget to clean and lube all mounting/slide points and pump up the brake pedal with the engine off before attempting to move vehicle and recheck fluid level.

Front Pad Replacement
Remove brake fluid until reservoir is half full.
Raise and support front of vehicle, then remove wheel and tire assembly.
Remove caliper guide pin and anti-rattle clips.
Remove caliper from disc by sliding caliper assembly out and away from braking disc. Suspend caliper with wire so as not to damage flexible brake hose.
Remove outboard brake lining, then lift off rotor and remove inboard brake lining.
Push piston back into cylinder bore with uniform pressure until it is bottomed.
Position inboard shoe and lining on adapter, then install rotor.
While holding outboard shoe in position on adapter, carefully position caliper over disc brake rotor.
Lower caliper over rotor and adapter.
Install guide pin through bushing, caliper and adapter.
Press in on guide pin and thread pin into adapter. Torque pin to 25 to 40 ft. lbs. on 1982 - 83 models and 25 to 35 ft. lbs. on 1984 - 87 models.
Install wheel and tire assembly, then lower vehicle.

Rear Pad Replacement
Raise and properly support vehicle.
Remove rear wheels, then clean caliper in area of access plug.
Remove access plug and insert a 4 mm Allen wrench through access hole, and engage retraction shaft. Rotate retraction shaft with Allen wrench counterclockwise to increase clearance between brake shoes and disc.
Remove outboard anti-rattle spring. Use care not to deform spring.
Back out the caliper guide pins to free caliper from adapter. Remove guide pins only if bushings or sleeve require replacement.
Lift caliper upward and away from disc. The inboard shoe will remain in caliper, attached to piston. Suspend caliper from a suspension member with suitable wire. Do not allow caliper to hang by brake hose.
Remove inboard shoe from piston (caliper) and outboard shoe from adapter.
When installing shoes and the caliper, note the following:
It will be necessary to retract the piston further with the Allen wrench due to the thickness of the new shoes. When retracting the piston, stop rotation of Allen wrench when slight resistance is encountered. This indicates that the piston has bottomed. Do not use excessive force since damage to retraction and actuation shafts may occur.
The inboard shoes are interchangeable and may be used on either side of the vehicle. The outboard shoes are not interchangeable and are marked "L" for left side or "R" for right side of vehicle.
Fit the retainer on inboard shoe into piston. Install proper outboard shoe on adapter. Lower caliper over disc and outboard shoe. Install and torque guide pins to 18---26 ft. lbs. Be sure not to crossthread the pins. Install anti-rattle spring.
To set the initial clearance between the brake shoes and disc, rotate the retraction shaft with the Allen wrench clockwise until snug, then back off 0.33 turn.
