Tech Tip: Reverse Bleeding Basics
Many vehicles can develop release problems after a clutch change or replacement of the hydraulic release system components; usually consisting of a clutch master cylinder, slave cylinder and line. Conventional bleeding is usually done by opening the slave cylinder bleeder valve and either gravity bleeding or pumping the clutch pedal while opening and closing the slave bleeder valve.
Tech Feature: Brake Job on Ford Edge
The Ford Edge is an SUV based on a the CD3 platform. The brakes on these vehicles are straightforward and do not break any new ground. The brake systems on all variants have disc brakes at all corners. There are no major changes to the brakes system from 2007 to 2009. For the 2008 model year, ABS became a standard feature, as did a direct tire pressure monitoring system. The worst brake component to service is the master cylinder. Getting to the unit requires removal of the trunking for the air intake, battery tray and other components.
Tech Tip: Volvo Brake Goes Too Low on First Application
If a customer complains of Volvo brakes going too low on first application, it may be because of improperly installed brakes or aerated fluid.
Tech Tip: Mazda ABS Warning Light On and Grinding Noise from Front Wheels
If a customer brings in a Mazda with an ABS warning light and a grinding noise from the front wheels, it could be due to problems with the sensor rotor or with the front brake disc, depending on the model.
Tech Feature: Brake Job on 2004-2008 Toyota Corolla
The 2004-2008 Toyota Corolla was one of the best selling vehicles in North America. The front brakes for all models are, for the most part, the same. The only changes came in the configuration of the brake pad shims. The Corolla was not subject to the unintended acceleration recalls for floor mats or gas pedal.
BRAKE JOB: Toyota Tundra Brake Caliper Upgrade
If a 2000-’05 Tundra or Sequoia comes into your shop with a complaint of brake pulsation, there are a few diagnostic steps that should first be taken before repairs are recommended.
Tech Tip: Some Facts About Brake Fluid Flushing
The purpose of the brake fluid is to transfer force under pressure from the master cylinder to the calipers/wheel cylinders. Non-contaminated fluid is imperative in order to maintain good brakeability, and to retain a high boiling point to prevent gassing and brake pedal fade.

Electronic Parking Brake (EPB) technology
Honda Tech Feature: Eliminating Brake Comebacks
The advent of ABS, and its integration into traction control and vehicle stability assist, make good work habits when servicing the brake
BRAKE JOB: GM H-Body Brake Job
Pad and rotor replacement is straightforward on this vehicle. But, there are some common errors that can be made if you are not paying attention. First, make sure the front caliper bracket bolts are tightened to 137 ft/lbs. If the bolts work their way loose, the driver may experience a sporadic low pedal condition or worse. Second, replace the hardware if necessary. Most noise complaints can be traced to worn out hardware. Third, this vehicle is sensitive to thickness variation of the rotors. Always make sure thickness variation is below .0005”, or you could have a pulsation comeback.
Tech Tip: Brake Vibration Diagnostics on Subaru Models
Studies confirm that rarely is it necessary to resurface brake rotors and/or drums on all four wheels when a confirmed brake vibration exists. With proper diagnostics, front or rear brake vibrations can be isolated, eliminating the need to resurface all four rotors and/or rear brake drums.
Brake Tech Feature: Rotors and Friction Service
Years ago, a brake replacement would pass muster if it allowed a vehicle to stop in a reasonable distance at highway speeds. Today, a brake replacement must meet consumer-oriented criteria in areas of braking noise, pedal sensitivity, side-to-side pulling, pedal pulsation, frictional qualities, fade resistance, wheel dusting and friction longevity.
