Recurring Brake Judder - Case Study

Originally the vehicle was taken into the garage to replace a worn set of front discs and pads.  After replacing the parts, the vehicle was test driven and the garage satisfied with the work that had been done. The vehicle was handed back to the owner and all appeared fine. However, a month or so later the vehicle returned to the workshop as the owner was now experiencing brake judder.

Why is there a need for different types of lubricant for the brake system?

For a braking system to be operating at optimum efficiency it is important to have free movement of components. Unfortunately, due to exposure to environmental conditions, being subjected to acidic cleaners and high-pressure washers, the brake area can suffer from corrosion that will inhibit free movement of components.

Brake Judder - Preventative Steps

Our articles Understanding brake judder and Bedding in & Material Transfer Process should have provided you with a better understanding of braking technology. Armed with that information, here is a helpful article on preventative steps that can be taken to prevent brake judder.

Bedding-in and Material Transfer Process

The “bedding-in” for brakes is essential for the brakes to perform optimally. Friction is key for efficient braking. Friction is a force resistant to movement between contacting areas. In braking there are 2 types of friction processes that occur during the material transfer process. To understand the bedding in process and material transfer process, we need to comprehend the difference between the 2 types of friction processes, which are the abrasive and adherent friction process.

Premature Wear of Outer Pad - A Case Study

This issue had spanned over a few months. It had started with the owner of the vehicle purchasing the vehicle and requesting for the brakes to be replaced. A few months after the brakes were replaced the owner reported of squealing noises at low speeds as well as a burning smell. Upon removing the front discs and pads, they discovered that the NSF outer (or finger side pad) had worn down considerably more than the inner pad.

Preventing NVH in vehicle braking systems

Vehicle manufacturers spend vast sums on R&D to reduce NVH (Noise, Vibration and Harshness). Here we explain why particular attention should be paid to NVH generated by the braking system.

ABS Sensors

An anti-lock braking system (ABS) is a vehicle safety system that allows the wheels of a car to maintain tractive contact with the road surface while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of cadence braking.

Directional Pads - observations for fitting

Directional brake pads differ from a traditional brake pad in their form, so measures need to be taken by fitters and technicians in order to minimise fitting issues.
