Rundown of Brake Service Chemical Applications
Penetrants for disassembly Brake system components are subjected to tremendous heat and can collect road salt, debris or other corrosive materials in the course of daily driving. Fasteners for calipers and caliper brackets are usually torqued to fairly high levels. The use of a quality penetrant at the start of brake service can ease and
What is Brake Noise? The Basics of Diagnosing NVH
What does your shop do when a brake noise complaint enters the service bays? Does it end up hurting productivity for the rest of the day as a technician randomly applies lubes, pastes and sprays to the brake system hoping that the problem will be at least temporarily solved? Brake systems are complex and require
Honda Brake Job Tips
Insight: Lightweight Rear Brake Drums The older Insight has a two-piece rear drum design with aluminum fins. The design borrows from the old 1950 Buick drums that had cast iron spun into an aluminum body. This design has significantly reduced weight over a cast iron drum. The use of aluminum fins on the outside helps

Brake Shims Provide Noise Control And Prevent Comebacks
The first thing to remember is that all brakes make noise. When the friction material makes contact with the rotor, the coupling causes the brake pad and rotor to oscillate and vibrate. In engineering terms, this is called “force coupled excitation,” which means that the components are locked as a combined system that will vibrate
Performing A Brake Job On A 2007-2013 Toyota Tundra
For 2007, the Toyota Tundra was redesigned. The body changed, and the foundation brake system was also updated with larger front brake calipers and rear disc brakes. The control system and hydraulics changed with a new vehicle stability system that included yaw, steering angle and brake pedal load sensors.
Diagnosing Nissan Front Brake Caliper Fluid Residue
While servicing 2005-’07 Maxima (A34), 2005-’06 Altima (L31) and
2007 Altima (L32 and H32 Hybrid Electric Vehicles-HEV), if you confirm there is oil residue on the brake caliper and it’s not assembly lubricant, refer to the Service Procedure as part of your normal brake diagnostic procedure.
Pay Close Attention To These Brake Hardware Items
If the caliper is not free to move, the culprit might be bent or binding mounting pins. Even if guide pins are not damaged, swollen or hardened guide seals or lack of lubrication may cause the caliper to bind resulting uneven pad wear. Always inspect all mounting surfaces and hardware for corrosion, wear or misalignment. Replace all mounting hardware and install a replacement caliper using the proper caliper lubricant.
Tech Tip: Nissan Front Brake Caliper Fluid Residue
If you confirm there is oil residue on the brake caliper and it’s not assembly lubricant, refer to the Service Procedure as part of your normal brake diagnostic procedure. Note: Castor oil assembly lubricant is applied to the brake caliper when it’s built and some residue is normal. Do not replace the caliper for castor oil residue.
Brake Service On A 2002-2009 Chevrolet Trailblazer
The Chevrolet Trailblazer is based on the GMT 360. The brake system on the Trailblazer is not groundbreaking by any means, but there are some intricacies technicians should be aware of on this common platform. The front brakes utilize dual piston calipers with phenolic pistons. The most important thing to remember when replacing the pads on this vehicle is to replace the hardware.
