It has started to shake when I apply the brakes

Hi,

Replacing front brake pads and rotors isn't too hard to do. Since they usually last around 25,000 miles, you can get life time parts and never have to pay for parts again.

Let's get started. First, here is a link that shows in general how it's done. You can use this as a guide when working on your vehicle:

Here are the directions specific to your vehicle. The pics below correlate with the directions.

Special Tools Required

- Brake Caliper Piston Compressor 07AAE-SEPA101

CAUTION
Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
- Avoid breathing dust particles.
- Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.

Inspection

1. Raise and support the vehicle See: Vehicle Lifting > Procedures.

2. Remove the front wheels.

3. Check the thickness (A) of the inner pad (B) and outer pad (C). Do not include the thickness of the backing plate.

4. If any part of the brake pad thickness is less than the service limit, replace all of the front brake pads as a set.

5. Clean the mating surface between the brake disc and the inside of the wheel, then install the front wheels.

Replacement

1. Remove some brake fluid from the master cylinder.

2. Raise and support the vehicle See: Vehicle Lifting > Procedures.

3. Remove the front wheels.

4. Remove the flange bolt (A) while holding the caliper pin (B) with a wrench. Be careful not to damage the pin boot, and pivot the caliper (C) up out of the way. Check the hose and pin boots for damage and deterioration.

5. Remove the brake pads (A) and the pad shims (B).

6. Remove the pad retainers (A).

7. Clean the caliper bracket (B) thoroughly; remove any rust, and check for grooves and cracks. Verify that the caliper pins (C) move in and out smoothly. Clean and lube if needed.

8. Inspect the brake disc for runout, thickness, parallelism See: Brake Rotor/Disc > Component Tests and General Diagnostics > Front Brake Disc Inspection, and check for damage and cracks.

9. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainer mating surface of the caliper bracket (indicated by the arrows).

10. Install the pad retainers. Wipe excess assembly paste off the retainers. Keep any assembly paste off the brake discs and brake pads.

11. Install the brake caliper piston compressor tool (A) on the caliper body (B).

12. Press in the piston with the brake caliper piston compressor tool so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.

NOTE: Be careful when pressing in the piston; brake fluid might overflow from the master cylinder's reservoir. If brake fluid gets on any painted surface, wash it off immediately with water.

13. Remove the brake caliper piston compressor tool.

14. Apply a thin coat of M-77 assembly paste (P/N 08798- 9010) to the pad side of the shims (A), the back of the brake pads (B), and the other areas indicated by the arrows. Wipe excess assembly paste off the pad shims and the brake pads friction material. Keep grease and assembly paste away from the brake disc and brake pads. Contaminated brake disc or brake pads reduce stopping ability.

15. Install the brake pads and pad shims correctly. Install the brake pad with the wear indicator (C) on the upper inside. If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a temporary loss of braking efficiency.

16. Pivot the caliper down into position. Install the flange bolt (A), and tighten it to the specified torque while holding the caliper pin (B) with a wrench being careful not to damage the pin boot.

17. Clean the mating surface between the brake disc and the inside of the wheel, then install the front wheels.

18. Press the brake pedal several times to make sure the brakes work.

NOTE: Engagement may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.

19. Add brake fluid as needed.

20. After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then check for leaks See: Brake Hose/Line > Component Tests and General Diagnostics.

1. Raise and support the vehicle See: Vehicle Lifting > Procedures.

2. Remove the front wheels.

3. Remove the brake hose mounting bolt (A).

4. Remove the brake caliper bracket mounting bolts (B), then remove the caliper assembly (C) from the knuckle. To prevent damage to the caliper assembly or the brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose excessively.

5. Remove the brake disc flathead screws (A).

pic 9

6. Remove the brake disc (B) from the front hub.

NOTE: If the brake disc is stuck to the front hub, thread two 8 x 1.25 mm bolts (C) into the brake disc to push it away from the front hub. Turn each bolt 90 degrees at a time to prevent the brake disc from binding.

7. Install the brake disc in the reverse order of removal.

NOTE: Before installing the brake disc, clean the mating surfaces between the front hub and the inside of the brake disc.

8. Inspect brake disc runout See: Brake Rotor/Disc > Component Tests and General Diagnostics > Front Brake Disc Inspection.

9. Clean the mating surface of the brake disc and the inside of the wheel, then install the front wheel.
