1. Intro to Disc Brakes

2. Most Common - Floating

3. Floating Disc Brake

4. Newton’s Law

5. Sliding – No Bolts

6. Sliding

7. Fixed – Caliper Does Not Move

8. Carbon Ceramic

10. Fixed Operation

11. Drum-In-Hat Parking Brake

12. Inside the Caliper

13. Caliper Piston Seal Flexes as piston moves out Pulls the piston back when brakes released Seals fluid self-adjusting

14. Brake Pads Backing plate Lining (pad) Wear indicators Clips, springs, hardware

15. Removing the Pads Remove brake fluid from m/c Retract piston first Remove caliper bolts Move caliper out of the way

16. Support Caliper Once removed, support caliper on wire or bungee cord Never let the caliper hang by hose

17. Pad Inspection

21. Brake Rotors Also called discs Rotating friction surface Vented for cooling

22. Heat Dam

23. Rotor Inspection

27. Just Started Making Noise

28. Parallelism / Thickness Variation

29. Runout

30. Runout Measurement

31. Economy Rotors

32. Burnish/Break-In Procedures Necessary to properly seat pads and rotors – Transfers a layer from the pads to the rotors Improves brake performance – Smoothes the mating surfaces – Heat cycles the pads and rotors Reduces noise

33. Procedures Vary - RTM For “normal” street service: 8 to 10 moderate applications from 40-10 mph is sufficient. Allow the brakes to cool for at least 15 minutes either by parking the vehicle or continuing to drive at moderate speeds with minimal brake applications.

34. Procedures cont. Make approximately 20 complete stops from 30-mph or 20 “slow downs” from 50-mph to 20-mph with light to moderate pedal pressure NO PANIC STOPS · Allow at least 30 seconds between brake applications for the brake pads or shoes to cool down No high speed stops and/or braking under heavy loads that could result in glazed or otherwise damaged linings

35. 30/30/30 Procedure Perform 30 stops from 30 miles per hour with a 30-second cooling interval between stops. Performed at a decelerating rate of 12 feet per second or less. This means that it should be a gentle easy stop. The 30/30/30 Burnish Procedure beds the pads and shoes into the rotor and drums. It also deposits the necessary friction transfer to the rotors and drums for optimum brake performance.
