Should I Clean Brand New Brake Pads

When servicing your brakes or installing new brake components it is vital that you clean your disc rotors when plumbing fixtures to reduce the take a chance of problems in the bedding-in stage. New and re-machined

rotors both require to be cleaned and wiped down before being fitted as the manufacturing process includes oils, graphite, carbon and silicone and new parts are by and large covered with a rust

protection picture show which tin all end up as residuum on the rotor. If not cleaned carefully at the time of being fitted these compounds and chemicals can impregnate the brake pads resulting in a

reduction in restriction functioning and an increase in the likelihood of squeaking or shuddering brakes.

The uneven wear of a disc rotor often referred to as Disc Thickness Variation (DTV) is where the disc varies in the thickness as indicated in the diagram below.

As the disc rotates through the caliper the variation in disc thickness results in a variation in braking force per unit area practical by the disc pads to the rotor. This variation in braking effort is translated

in vibration that tin exist felt through the vehicle such as pedal pulsation, steering wheel oscillation and vibration through the floor of the vehicle.

A number of suggestions are recommended by Bendix to avoid these problems. These include using a medium to fine grit emery on the rotor whilst all the same spinning later machining and ensuring the disc is completely free of burrs. Spraying with a noncorrosive, not staining restriction cleaner such as Bendix Brake/Parts Cleaner and Degreaser to remove any rust protection from new rotors and to clean abroad whatsoever residuum from machined parts is essential to ensure these are completely make clean.

Bendix Brake/Parts Cleaner and Degreaser is specifically recommended for the cleaning procedure every bit it contains no Cfc's, is ozone friendly and finer removes all impurities. The product can be used on all restriction parts including brake assemblies, ABS, brake drums, disc pad backing plates, calipers and bicycle cylinders. It is also platonic for use on other degreasing jobs effectually the workshop leaving surfaces rest free, clean and dry.

Bendix Brake/Parts Cleaner and Degreaser is designed to penetrate quickly, clean instantly and evaporate apace. It can also be applied without disassembling the brakes. All components can then exist wiped off with a clean soft fabric.

DTV often does non become apparent until 10,000 to 15,000 kms after disc machining or replacement and poorly serviced calipers can accelerate the occurrence of DTV, as tin high levels of rotor run-out at fitment (greater than 0.10mm). You can measure the disc thickness of the rotor 25mm in front of the outer edge using a Vernier caliper.

This measurement should be taken at a minimum of ten points around the circumference and at that place should be no greater than 0.03mm variance in whatsoever of the measurements. If greater, the rotor should exist replaced or machined with a light skim to clean up any DTV flat spots. If the vehicle is using ceramic pads the rotor must be machined on every restriction chore. Calipers should be overhauled, side pins must move freely and the piston seals must be checked for good condition or replaced. Onvehicle machining eliminates variation in axles, bearings etc.

If at that place is zip rotor run-out at fitment then DTV will non happen. Unfortunately vehicle blueprint, tolerance variations and general vesture and tear may mean that zero rotor run-out is unachievable.

However, on-vehicle measurement of rotor run-out with an accurate dial indicator combined with the utilise of a good quality torque wrench to tighten the wheel basics will minimise run-out and minimise DTV effects.

Installed run-out should exist less that 100µm (0.1mm) and when this cannot be accomplished checks on the bearings, flange, stub beam and rotor hat should be fabricated. Wheel basics should be evenly

torqued with the use of a torque wrench to avoid distortion.
