i have a new grand caravan with disks in the rear. i would like to know the exact proceedure to service these brakes. i want to remove the linings and clean the runners and lubricate them. been noticing a bit move scrapping on the rears and think the pads aint floating as they should. also please let me kow if i require any special tools to perform this cause of rear parking brake adjustment.

REMOVAL





NOTE:Before proceeding, .1.Raise and support vehicle.
NOTE:Perform Step #2 through Step #8 on each side of vehicle to complete pad set removal.2.Remove wheel mounting nuts (3), then tire and wheel assembly (1).



CAUTION:When removing or installing a caliper guide pin bolt, it is necessary to hold the guide pin stationary while turning the bolt. Hold the guide pin stationary using a wrench placed upon the pin's hex-shaped head.
3.Remove two caliper guide pin bolts (1).4.Remove the disc brake caliper (2) from the disc brake adapter bracket and hang it out of the way using wire or a bungee cord. Use care not to overextend the brake hose or parking brake cable when doing this.


5.Prior to pad removal, inspect for freedom of pads to slide on caliper adapter.6.Remove the brake pads (2, 5) from the caliper adapter bracket (3).


7.If pads show signs of very uneven wear, and/or pads did not slide easily on adapter, replace adapter bracket. Remove two mounting bolts (2) and remove bracket.8.If pads did not show signs of very uneven wear, remove and discard old pad shims, and clean abutments (area behind shims) of any debris or corrosion.

INSTALLATION








NOTE:Perform Step #1 through Step #7 on each side of vehicle to complete pad set installation, then proceed to Step #8
CAUTION:Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the parking brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor, Rear Caliper Piston 8807 , as described below. Any other seating method will damage the self-adjuster mechanism.

1.If necessary, seat (bottom) the caliper piston in the bore as follows: a.Assemble a 3/8 in. drive ratchet handle and an extension (3).b.Insert the extension through Special Tool 8807-1 (2).c.Place Special Tool 8807-2 (1) on the end of the extension.d.Insert lugs on Special Tool 8807-2 into notches in face of caliper piston (5).e.Thread the screw drive on 8807-1 down until it contacts the top of 8807-2 which is against the caliper piston. Do not over tighten the screw-drive. Damage to the piston can occur.f.Turn 8807-2 with the ratchet, rotating the piston in a clockwise direction until fully seated (bottomed) in the bore. It may be necessary to turn 8807-1 with 8807-2 to start the process of piston retraction.

2.If caliper adapter was replaced, install caliper adapter bolts (2) and tighten to 100 N-m (74 ft-lbs).



NOTE:There are two different abutment shims. If installed in wrong orientation, pads will not fit properly.
NOTE:If the brake pads have a protective paper on the rear face of the brake pad plate, it must be removed before pad installation.3.Assure adapter abutments are free from debris or corrosion. Apply an even layer of Mopar© Brake Lubricant or equivalent to entire area of four abutments PRIOR to shim installation. Install four new pad shims (4). 4.Place the brake pads (2, 5) in the abutment shims (4) clipped into the disc brake caliper adapter bracket (3) as shown.



CAUTION:Use care when installing the caliper (2) onto the adapter bracket to avoid damaging the guide pin boots.
CAUTION:When removing or installing a caliper guide pin bolt, it is necessary to hold the guide pin stationary while turning the bolt. Hold the guide pin stationary using a wrench placed upon the pin's hex-shaped head.
5.Install the disc brake caliper (2) over the brake pads on the brake caliper adapter bracket.6.Align the caliper guide pin bolt holes with the adapter bracket. Install the upper and lower caliper guide pin bolts (1). Tighten the guide pin bolts to 35 N·m (26 ft. lbs.).


7.Install tire and wheel assembly (1) (Refer to 22 - Tires and Wheels - Installation) . Install and tighten wheel mounting nuts (3) to 135 N·m (100 ft. lbs.).8.Lower vehicle.9.Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.10.Check and adjust brake fluid level as necessary.11.Road test vehicle and make several stops to wear off any foreign material on brakes and to seat brake pads.

 

Sorry to hijack thread but after doing this exact procedure, my parking brake doesn't seem to engage very well if at all everything looks good as I was careful not to disconnect anything. What may cause this?

 

i yet to do this. but i just servicing them so no need to actually push in the caliper. only if u replacing the pads. did the fronts yet to do the rear.
