Disc/Drum Machining & Cleaning

An introduction to Disc/Drum Machining & Cleaning

Disc/Drum Machining & Preparation

  1. Machine disc/drum using the slowest feed rate. Do not take heavy cuts. The final cut should be minimal depth to minimise any grooving on the surface.
  2. After machining, clean the disc/drum with 240 grit emery on both surfaces (do this while the disc/drum is spinning on the lathe) to obtain a smooth non-directional surface finish.

Disc/Drum Machining & Preparation

  1. Disc/drum machining may leave a fine film of graphite on the disc/drum surface. Always clean down the disc/drum surfaces using Bendix Ceramasil Brake Parts Lubricant after machining. Never use petrol as it contains waxes which can remain on the disc/drum surfaces after the solvents evaporate. The waxes act as a lubricant, reducing braking efficiency.
  2. After fitting, once again wipe down the disc/drum. Only use a clean rag and Bendix Brake Cleaner & Parts Degreaser.

Bedding-In Procedure*

To maximise the performance of brake pads, it is essential that they are bedded in correctly as follows:

  1. Accelerate vehicle to 50km/h
  2. Apply brakes using moderate to firm pedal effort, reducing speed to 5 km/h
  3. Drive 200m – 300m accelerating to 50 km/h
  4. Repeat steps 1 to 3 between 8 - 10 times

* No Bedding-In procedure required for products that feature Blue Titanium Stripe.
