Before starting, if your brake master cylinder is very full, draw off some of the fluid. When you push back the caliper pistons, if the master cylinder is completely full, it can overflow. BRAKE FLUID DESTROYS PAINT.
1. Jack up one side of the car. Put a jack stand under the rear torsion bar end cover. (Figure 1)
2. Remove the wheel.
3. There are two pins holding the pads in each caliper. The front pins have self-retainers, and can simply be tapped out from the outside, using a pin punch or a nail. The retaining pins in the rear calipers have little hairpins (Figure 2) in the inboard end of each pin, which must be removed before the pin can be tapped out. (Figure 3) After you remove one of the retaining pins, you can take out the brake cross-spring. Note how it fits before removal, so you can get it back in right. (Figure 4)
5. Push the both pistons all the way back into the caliper. To do this, you can use a piece of hard wood, or a pair of channel-lock pliers. Just be careful not to damage or ding anything. (Figure 7)
6. Inspect the rotors. If they have severe ridges, or if they are worn below the minimum thickness, they will need to be resurfaced or replaced. The same is true if they are warped or have excessive runout (a symptom of warpage or runout is steering wheel shimmy when you apply the brakes). (Figure 8)
7. Inspect the calipers. If they are leaking fluid, or if the rubber dust boot is damaged, they will need to be rebuilt or replaced. Rust on the exposed part of the piston, next to the brake pad, is normal. (Figure 9)
8. Inspect the brake hoses for cracking or leakage. (Figure 10)
9. This is also a good time to inspect the shock absorbers. Any evidence of fluid leakage indicates need for replacement. (Figure 8)
10. If the inspection of the rotors, calipers, and brake hoses is satisfactory, proceed with the installation of the new pads.
11. Do not use the anti-squeal compound pad from your Friendly Local Auto Parts Store on the back of the brake pads. This stuff turns to glue, and when you need to replace the brake pads again, it will destroy the caliper dust boot when you pull the pads out (don't ask how I know this). Many new brake pads come with an anti-squeal coating already applied. It looks like a thicker coat of paint on the back of the pads. If you want to use something more I recommend a LIGHT coat of Lubro-Moly Hi-Tack Lube Spray. Be careful not to get this stuff on the braking surface of the pads, or on the rotors. (Figure 11)
12. Insert the new pads the same way the old ones came out. Reconnect the sensor wires, if so equipped. (Figure 12)
13. Insert one of the retaining pins, taking care that the hole for the hairpin in the retaining pins of the rear calipers is accessible. Tap each pin until it is fully seated. You should be able to see the end of the pin in its hole on the outside of the caliper.
14. Insert the hairpin into the brake pad retaining pin.
15. Insert the brake cross spring (Figure 13), and then the second retaining pin. Make sure that both ends of the brake cross spring engage the retaining pins. The cross spring helps retract the pads, so they don't drag on the rotors when you let off the brakes.
16. Repeat steps 2-15 for the other three calipers.
17. Reinstall the wheels. The correct torque for factory alloy wheels and alloy lug nuts is 95 ft/lbs.
18. Top off the master cylinder. Use only fresh fluid from a sealed container. We recommend a top-quality fluid such as Ate.
19. Pump the brake pedal a few times to return it to normal position.
20. Recheck the master cylinder brake fluid level.
CAUTION: New brake pads require a break-in period. Until they are broken in, braking efficiency is reduced. Apply the brakes gently during break-in to increase the life of pads and rotors.
It is not necessary to bleed the brakes after this procedure. However, it is a good idea to completely flush and bleed the brake system at least every two years.
