Brake Pad: Service and Repair

REMOVAL

1. Hoist vehicle and remove wheel.





2. Remove caliper pin bolts.





3. Remove E-ring from strut and then remove caliper from caliper carrier.

NOTE: Hang removed caliper with a wire hook or the like so as to prevent brake hose from bending and twisting excessively or being pulled. Don't operate brake pedal with pads removed.

4. Remove pads.

INSPECTION
Brake Pad





Check pad lining for wear. When wear exceeds limit, replace with new one.

CAUTION: Never polish pad lining with sandpaper. If lining is polished with sandpaper, hard particles of sandpaper will be deposited in lining and may damage disc. When pad lining requires correction, replace it with a new one.

Pad thickness (lining + rim):
Standard: 15.0 mm (0.590 inch)
Service limit: 6.0 mm (0.240 inch)

NOTE: When pads are removed, visually inspect caliper for brake fluid leak. Correct leaky point, if any.

Brake disc





Before this inspection, brake pads must be removed. Check disc surface for scratches in wearing parts. Scratches on disc surface noticed at the time of specified inspection or replacement are normal and disc is not defective unless they are serious. But when there are deep scratches or scratches all over disc surface, replace it. When only one side is scratched, polish and correct that side.
Disc thickness:
Standard: 20 mm (0.79 inch)
Service limit: 18 mm (0.71 inch)





Mount a dial indicator as shown and measure the runout at 25 mm (0.98 inch) from the outer edge of the disc.

Limit on disc deflection: 0.1 mm (0.0039 inch)

NOTE: Check front wheel bearing for looseness before measurement.

Cylinder slide bush





Check slide pin (bolt) for smooth movement as shown. If it is found faulty, correct or replace. Apply rubber grease to slide pin (bolt) outer surface. Rubber grease should be the on whose viscosity is less affected by such low temperature a -40°C (-40°F).

INSTALLATION

NOTE:
^ All brake fasteners are important attaching parts in that they could affect the performance of vital parts and systems, and/or could result in major repair expense. They must be replaced with one of same part number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to assure proper retention of all parts. There is to be no welding as it may result in extensive damage and weakening of the metal.





1. Install pad shims and pads.





2. Install caliper and torque caliper (slide) pin bolts to specification.
Tightening Torque (a): 22 Nm (2.2 kg.m, 16.0 ft. lbs.)

NOTE: Make sure that boots are fit into groove securely.





3. Torque front wheel nuts to specification.
Tightening Torque (a): 85 Nm (8.5 kg.m, 61.5 ft. lbs.)
4. Upon completion of installation, perform brake test.
