There is debris such as small stones, grit, road salt or sand between the brake disc and pad. 5. Discs are covered in rust. Rust can form when the vehicle has been stationary for long periods of time (Figure 1). 6. Discs have a groove in them (Figure 2) 7. There is chemical contamination on the braking surface of the disc due to a wheel or tyre cleaner being sprayed directly onto the disc (Figure 3). 8. There are pad marks on the brake disc as a result of the brake pad material transferring to the discs. This can occur when a vehicle has been stood for long periods of time in a wet or snowy environment (Figure 4). |

This includes potential air leak points on the air springs and also the locations of an air leak that can be repaired without the need to replace an air spring. Please follow and complete the check list within the Measure section of this TPI to help in diagnosing the issue (the check list does not need to be sent as an attachment should a DISS technical query be raised) . Should a leak be found from an air spring, compressor, valve unit or reservoir, please raise a DISS technical query and include as much information as possible including photograph/s of the leak/s location. Once the DISS ticket has been submitted please await clarification from your TSC before commencing with replacing any of the suspected faulty air springs.
