It developed a vibration in the front

Hi,

Replacing brake pads and rotors isn't too difficult. In general, you can expect them to last around 25000 miles before being worn down. However, that is based on driving habits.

First, here is a link that shows in general how to replace front brake pads and rotors on a front wheel drive:

Now, the Tazz isn't offered in the US. However, I believe it is the same as our Toyota Corolla, so I will provide the directions for that vehicle. The attached pics correlate with the directions. Note: These directions cover caliper repair and rotor inspection.

11. REMOVE FRONT DISC BRAKE PISTON
a. Place a piece of shop rag or equivalent between the piston and the disc brake cylinder assembly.
b. Use compressed air to remove the piston from the disc brake cylinder assembly.

CAUTION: Do not place your fingers in front of the piston when using compressed air.

NOTICE: Do not spatter the brake fluid.

12. REMOVE PISTON SEAL
a. Using a screwdriver, remove the piston seal from the disc brake cylinder assembly.

NOTICE: Do not damage the inner cylinder and cylinder groove.

13. REMOVE FRONT DISC BRAKE BLEEDER PLUG
14. INSPECT BRAKE CYLINDER AND PISTON
a. Check the cylinder bore and piston for rust or scoring.
If necessary, replace the disc brake cylinder assembly and piston.

15. INSPECT PAD LINING THICKNESS
a. Using a ruler, measure the pad lining thickness.
Standard thickness: 11.0 mm (0.433 inch)
Minimum thickness: 1.0 mm (0.039 inch)
If the pad lining thickness is equal to the minimum thickness or less, replace the brake pad kit front.
16. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
a. Make sure that both plates have sufficient rebound, have no deformation, cracks or wear, and that all rust and dirt are cleaned off.
If necessary, replace the pad support plate (No.1).
17. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
a. Make sure that both plates have sufficient rebound, have no deformation, cracks or wear, and that all rust and dirt are cleaned off.
If necessary, replace the pad support plate (No.2).

18. INSPECT DISC THICKNESS
a. Using a micrometer, measure the disc thickness.
Standard thickness: 25.0 mm (0.984 inch)
Minimum thickness: 23.0 mm (0.906 inch)
If the disc thickness is less than the minimum, replace the disc.

19. REMOVE FRONT DISC
a. Put matchmarks on the disc and the axle hub.
b. Remove the front disc.
20. INSTALL FRONT DISC
a. Aligning the matchmarks, install the front disc.

NOTICE: When replacing the disc with a new one, select the installation position where the front disc has the minimum runout.

21. INSPECT DISC RUNOUT
a. Check the bearing play in the axial direction and check for the axle hub runout.
b. Temporarily fasten the front disc together with the hub nuts.
Torque: 103 Nm (1,050 kgf-cm, 76 ft. lbs.)
c. Using a dial indicator, measure the disc runout 10 mm (0.39 inch) away from the outer edge of the front disc.
Maximum disc runout: 0.05 mm (0.0020 inch)
If the runout exceeds the maximum value, change the installation positions of the disc and axle so that the runout will become minimal. If the runout exceeds the maximum even when the installation positions are changed, grind the disc. If the disc thickness is less than the minimum, replace the front disc.
22. TEMPORARILY TIGHTEN FRONT DISC BRAKE BLEEDER PLUG
23. INSTALL PISTON SEAL
