BEST PRACTICE BRAKE REPLACEMENT
Scott Irwin MIMI, Head of Technical Training at TMD Friction’s aftermarket brake brand, Mintex, tells us more...
Being at the forefront of braking technology for more than 100 years, Mintex has continued to provide a complete aftermarket solution, delivering high braking standards and safely braking millions of families and motorsport champions worldwide.
However, while most mechanics concur with Mintex’s exceeding standards and replace brakes efficiently, some are cutting corners to save time, meaning simple tasks such as cleaning rust and dirt are often overlooked. Here, Mintex provides best practice tips, making sure these simple, yet effective steps aren’t ignored, which ultimately ensures customers don’t return with complaints such as brake judder.
What’s the first stage of the brake repair process?
Before beginning to repair the brakes, it’s key to look for uneven wear on the discs, as well as checking all components surrounding the axle and examining the hydraulic system or any broken parts. Parts showing signs of heavy wear or defectiveness should be replaced in accordance with the vehicle, system and brake manufacturer’s guidelines.
When dismantled, it’s imperative to remove any rust or residue from the contact surfaces and caliper bucket as this can result in brake judder, which gives a vibration through the brake pedal or steering wheel. To prevent the likelihood of brake judder, use a wire brush or a hub grinder (product code: MTL1018) to get rid of any rust from the contact surfaces and hub flange. Once removed, use a brake cleaner to clean the surface and check the cleaned hub with a measuring gauge, such as a DTI gauge (product code: MTL1033), for any possible lateral run-out deviations.
During the cleaning process, it’s important to take great care not to damage the caliper bracket.
What lubricant do you need to use?
Grease the newly cleaned areas with a non-conductive, heat-resistant and solids-free agent such as Mintex Ceratec Advanced Lubricant. Do not apply to the brake surface, or on the back of the pad where is has
