DISC BRAKE PADS – FITMENT GUIDE

SAFETY & WARNINGS

Disc Brake Pads and their related system components are safety critical. Do not undertake fitment if you are unable to do so in a competent trade like manner.
This is a general fitment guide and any vehicle specific workshop procedures must be followed as per the manufacturers workshop manuals.
Correctly support vehicle weight with axle stands before placing any part of your body under the vehicle.
Brake fluid handled in an inappropriate way may cause serious personal injury or damage, particularly to painted surfaces.
Do not use compressed air to clean brake components. Do not breathe in fine dust from brake components as this can be a health hazard. If working in poorly ventilated areas, use a respirator.

Step 1: Raise Vehicle

Chock appropriate wheel axle set. Raise/Jack vehicle and install axle safety stands. Remove wheel and work on one axle at a time (this is important as you can use the other side for reference if you have problems with reassembly). As an extra safety measure place removed wheel under the appropriate front or rear chassis centre between the axle stands or under engine cross bar.

Step 2: System inspection and Disc Brake Pad removal

Review the brake assembly and its components. Take note of the brake caliper type as there are different procedures for “fixed” brake calipers versus “sliding” brake calipers. Examine Brake Disc Rotor for scoring and/or tapered wear. Measure the rotor thickness. Resurface brake rotors if required. If below minimum then replace.

Fixed Caliper
Review pad retaining hardware. Remove retaining bolts or pins and associated spring clips. Attach brake bleeding bottle or vacuum bleeder to bleed screw. Check master reservoir level is not low. Release caliper bleed screw. Use a clamp or expansion tool to push pads back, or back off disc brake pads 2-3mm, then remove from caliper and continue piston retraction with appropriate tool. Inspect caliper piston, piston dust boots and general caliper condition. Damage to any components and or any fluid leaks would require caliper rebuild or replacement.

Sliding Caliper
Review caliper body retaining hardware. Loosen bleed screw and softly retighten (as it is difficult to undo the bleed screw later with caliper body loose). Remove caliper body retaining bolts or slide pins. Remove caliper body (In some cases you can remove just one retaining bolt and pivot caliper to expose Disc Brake Pads). Remove Disc Brake Pads. Attach brake bleeding bottle or vacuum bleeder to bleed screw. Check master reservoir level is not low. Release caliper bleed screw. Use a clamp or expansion tool to push pistons back to home position. Inspect caliper piston, piston dust boots and general caliper condition. Damage to any components and or any fluid leaks would require caliper rebuild or replacement. Inspect caliper carrier, slides and dust boots. If required, clean and lubricate caliper slides with special grease. Damaged or rusty slides/guides will require replacement.
