Rear Disc Brake Pad Replacement Info for Dodge Caravan
Just thought I would throw this out here for the community. I replaced my rear disc brake pads (08 Grand Caravan) today and found out that I needed a special tool (from AutoZone, free for use) or had to use a C clamp to compress the caliper and screw in the caliper piston at the same time. I did a search here and on the net and didn't find this information out. Luckily my Brother who is a mechanic told me the trick to compressing the caliper piston. Hopefully this will help others like me that were unaware of this, I'm sure this is not something new. I used to work on my own cars allot, but got away from it and now have started back doing my own work (crappy economy).

The 5th Generation have the screw type parking brake for their rear discs. Here's information on the two commonly used systems (Toyota, but don't let it scare you). http://www.autoshop101.com/forms/brake06.pdf

INSTALLATION
Perform Step #1 through Step #6 on each side of vehicle to complete pad set installation, then proceed to Step 7
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, Special Tool 8807, as described below. Any other seating method will damage the self-adjuster mechanism.
<A xmlns="http://www.w3.org/1999/xhtml">
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.
<A xmlns="http://www.w3.org/1999/xhtml">
2.Make sure abutment shims (4) are in place on both upper and lower slide abutments of caliper adapter (3).
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.Place the brake pads (2, 5) in the abutment shims (3) clipped into the disc brake caliper adapter bracket (3) as shown.
<A xmlns="http://www.w3.org/1999/xhtml">
CAUTION: Use care when installing the caliper (2) onto the adapter bracket to avoid damaging the guide pin boots.
4.Install the disc brake caliper (2) over the brake pads on the brake caliper adapter bracket.
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.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.).
<A xmlns="http://www.w3.org/1999/xhtml">
6.Install tire and wheel assembly . Install and tighten wheel mounting nuts (3) to 135 N·m (100 ft. lbs.).
7.Lower vehicle.8.Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.9.Check and adjust brake fluid level as necessary.10.Road test vehicle and make several stops to wear off any foreign material on brakes and to seat brake pads.

2001 Viper ..... interesting. Some blame the screw type design on General Motors. Don't know where it originated. Seen it used on Hondas for several years.
