Achieving better braking performance
Failure to clean rust buildup and properly lubricate caliper brackets during brake service is proven to be a major cause of brake noise, premature wear and increased stopping distance. The Garage Gurus recommend a meticulous cleaning and lubricating of all caliper brackets and mounting points. This will allow proper caliper/pad movement to ensure maximum brake performance and customer satisfaction.
During this cleaning you should address the following issues:
Pad Guide Rust/Corrosion
Pad Rust Buildup
Rust Jacking – No Pad Movement
Recommended caliper cleaning & lubrication procedure:
- Use a wire brush or sand/bead blasting to remove rust from caliper brackets/guides to achieve a clean, smooth, uniform surface.
- Clean or replace attaching hardware.
- Lubricate metal-to-rubber friction points (guide pins to boots) with silicone lube (Wagner #F132005).
- Lubricate metal-to-metal friction points (brackets to guides/guides to pads) with a Molybdenum Disulfide lube, commonly called Moly Lube.
- DO NOT lubricate or apply any compounds on the backing plate of Wagner ThermoQuiet® pads with IMI brake pads.
- Use premium quality Wagner brake pads.
- Use Wagner rotors.
Note: Molybdenum Disulfide is effective in wet or corrosive environments over a wide range of temperatures.
After a thorough cleaning and lubrication, here is what a cleaned caliper bracket and properly lubed guide pins and guides look like.
