Changing Brakes on 2005 - 2008 SRT8 Vehicles

How to change the Brakes on 2005-2008 SRT-8 Vehicles
Knowing that many people like to work on their own vehicles, we thought we would provide a general How-To article on some of the more popular repairs. This article will show you the basic steps involved in changing the Brembo style brakes on the popular LX SRT-8 vehicles as well as the Grand Cherokee SRT-8. The first sections describe how to change the brake pads followed by instructions for changing the calipers if needed. Now this is a safety system of the vehicle, if you do not feel comfortable in doing this repair then please take your vehicle to an authorized service center near you. There may be some additional details that may not be included in this article that may also need to be done to complete the repair properly. This article is designed for technicians who have experience with these type of repairs and know what else may be required.

BRAKE PAD REMOVAL FRONT - SRT8
1. Raise and support vehicle.
2. Remove the front tire and wheel assembly.
3. Using hammer (1) and pin punch (2) on outboard end, tap the lower brake pad support pin (3) out of caliper (5).
4. Remove brake pad spring clip (4) out from under the upper support pin (3) still in caliper.
5. Using pin punch (2) and hammer (1), remove upper brake pad support pin (3) in same manner used on lower support pin.
CAUTION: When pushing pistons back into caliper bores, if hand pressure is not sufficient, use only a trim stick or other suitable soft tool to do so. Never use a screwdriver or other metal pry bar due to potential damage to braking surface of rotor or pads.
6. Using hand pressure, pull pads back to seat caliper pistons into bores if possible. If not possible, perform the following to do this correctly without damaging the caliper, pistons, dust boots or brake rotor disc.
- Place trim stick between inboard brake pad and outer edge of rotor.
- Using trim stick, apply pressure against the inboard brake pad until both pistons are completely bottomed in bores of inboard caliper half. Leave trim stick in place to hold pistons in place.
- Place second trim stick between outboard brake pad and rotor, then repeat above step on outboard pad and pistons.
NOTE: Once brake pads are removed from caliper, inspect all four caliper pistons and dust boots for evidence of brake fluid leakage. Also inspect dust boots on all caliper pistons for any cuts, tears or heat cracks and brake pad supports (if equipped) for excess wear or damage. If caliper fails inspection, it should be replaced.
7. Remove inboard brake pad (2) through opening in caliper (3). Remove outboard brake pad (1) in same manner.

| BRAKE CALIPER REMOVAL FRONT - SRT8
NOTE: These calipers are not serviceable. Do not attempt disassembly.
1. Disconnect and isolate battery negative cable.
2. Install prop rod on the brake pedal to keep pressure on the brake system, Holding pedal in this position will isolate master cylinder from hydraulic brake system and will not allow brake fluid to drain out of brake fluid reservoir while brake lines are open. This will allow you to bleed out the area of repair instead of the entire system. 
3. Raise and support vehicle.
4. Remove the tire and wheel assembly.
5. Remove banjo bolt (3) connecting flexible brake hose (2) to caliper (1). There are two sealing washers (one on each side of the hose fitting) that will come off when bolt is removed. Discard these washers; use NEW washers upon installation.
CAUTION: When pushing pistons back into caliper bores, use only a trim stick as shown or other suitable soft tool. Never use a screwdriver or other metal pry bar due to potential damage to braking surface of rotor, caliper, pistons or dust boots.
6. Place trim stick between brake pad and outer edge of rotor.
7. Using trim stick, slowly apply pressure against brake pad until both pistons (on that side of caliper) are completely bottomed in bores of caliper half.
NOTE: Repeat above procedure to opposite brake pad and pistons as necessary.
8. Remove caliper mounting bolts (4).
9. Remove brake caliper (1) with pads from knuckle and brake rotor.
