Removal & Installation


NOTE Using a brake pedal holding tool, depress the brake pedal past its first inch of travel and hold it in this position. This will isolate the master cylinder from the hydraulic brake system and will not allow brake fluid to drain out of the reservoir while the brake lines are open.

1. Before servicing the vehicle, refer to the Precautions section.
2. Remove or disconnect the following:
   
   Negative battery cable Rear wheels Banjo bolt retaining the brake hose to the caliper. Be sure to plug the end of the brake hose or cover it with a plastic bag to prevent contamination from entering the hydraulic system. Caliper guide pin bolts Caliper assembly from the brake adapter by rotating the bottom of the caliper away from the rotor, then lift the caliper with the pads away from the adapter abutment Brake pads by pushing (outboard) or pulling (inboard) from the caliper fingers and piston

To install:

1. Completely compress the caliper piston
2. Install or connect the following:
   NOTE The outboard pads are side oriented, make sure the spring clip is installed so it is positioned downwards when the caliper is installed.
   
   
   Inboard pad clip against the piston cavity and press the pad until the clip is seated making sure the pad backing plate is flush against the piston
   
   
   Outboard pad making sure the locating pins are positioned against the ramps. Slide the pad onto the caliper and ensure the locating pins are squarely seated into the holes on the caliper and the pad is flush against the caliper fingers.
   
3. Make sure the abutment shims are in place on both slide abutments.
4. Retract the caliper guide pins to clear the caliper adapter bosses.
   
   Brake caliper. Staring with the upper end, position the caliper and shoes over the rotor and align the outboard pad upper edge with the caliper slide abutment. Rotate the lower end of the caliper into position Caliper guide pin bolts and tighten to 200 inch lbs. (23 Nm) Banjo bolt with new washers on each side of the hose fitting and tighten to 35 ft. lbs. (47 Nm) Wheels Negative battery cable
   
5. Bleed the brake system and road test the vehicle

Front brakes are very simple to do:

• Pull off the front tires.
• Remove the brake pads by removing the slide pin bolts where the piston assembly attaches to the caliper mounting bracket. The slide pin bolts are usually a 12 or 14mm bolt. Once the piston assembly is free slide the old brake pads out.
• Compress the piston back into the caliper by using a large pair of channel lock pliers or a c-clamp. If you don't do this, you won't be able to get the new pads on.
• Before you put the new pads on, replace the rotor.
• Remove the two bolts for the caliper mounting bracket. They are in the back and are bigger than the slide pin bolts. Usually a 17 or 19mm bolt.
• Pull off the caliper mounting bracket.
• At this point the old rotor should slide right off. If it doesn't slide right off, look for a screw in the center of the rotor, some cars will have a screw there to hold the rotor on. If there's no screw and it still won't come off, try tapping it with a hammer. If you're replacing the rotor, don't be shy.
• Put the new rotor on. Make sure to clean off any grease with brake cleaner that may be on the braking surface from packaging.
• Put the caliper mounting bracket back on.
• Put the new brake pads on. Make sure to use some anti-squeal grease on the back of the pads.
• Put the caliper assembly back on with the slide pins. Grease up the slide pins as well.
• Put the wheels back on.
• Make sure to pump your brakes 10 - 15 times before you drive off. Because you compressed the piston back into the caliper, the piston will not be contacting the brake pads unless you pump the brakes.

Good Luck!

To remove the brake rotor, you must first remove the brake pads and caliper. There are two bolts that hold the brake caliper in place. Remove the two bolts and tie the caliper up out of the way. Be careful not to break the brake line connected to the back of caliper. Once the caliper is removed, simply slide the rotor off. To install a new rotor, simply slide rotor over studs and replace the caliper with new brake pads. It is as simple as that.
