What Makes a Quality Brake Job
Brake repairs are one of the most common vehicle services. With so many shops doing them and such a variety of advertised ‘brake specials’ and prices how do you know if your brakes are being done properly and you are receiving good value for your money? Remember, cheap pricing usually comes with compromises in quality of parts and workmanship. Here’s what makes a good brake job.
It starts with a thorough inspection and that begins with a road test. The technician looks for brake pulls and vibrations when the brakes are applied and listens for noises. In the shop comes is a visual inspection of the brake fluid, looking for fluid level and quality of the fluid. The master cylinder and brake booster are visually inspected as are all brake lines and hoses. Wheels are then removed and brake pads and shoes are measured for thickness and evenness of wear. Brake rotors and drums are also measured for thickness and inspected for damage. Calipers and wheel cylinders are inspected for leakage and freedom of movement. Also visually inspected are ABS wires and proportioning valves and let’s not forget the operation of the parking brake. Other incidental but critical items safe braking are inspected such as wheel bearing play, shocks and struts and obviously loose steering and suspension components.
From the inspection an assessment of the brakes is made: which parts are in good condition and functioning well, and which items need repair now. A good shop will consult with you about how much you drive and where. This helps determine the urgency of repairs.
Let’s now look at repairs. A quality brake job involves not only replacement of parts but also thorough cleaning: caliper and pad sliders frequently get corroded and using a wire wheel or sandblaster to remove rust is essential. Hardware and self-adjusters for drum brakes requires disassembly and cleaning. After cleaning, components require lubrication with quality high temperature brake lubricants.
Quality of parts is very important to a successful trouble free repair: there are many grades of brake parts and using the best quality makes sense for longevity and the best stopping power. Cheap parts usually wear out faster; will cause squeals and other unwanted concerns.
Flushing brake fluid is a service often required with a brake job. Brake fluid absorbs water right out of the air and becomes contaminated. Many manufacturers recommend replacing the fluid every 2 years. When due, this becomes part of a quality brake repair.
After repairs, a thorough road test is done to be sure that your brakes are stopping your car as they should. Be aware that after many brake repairs you may find that your brakes make different sounds, the pedal feels different and there may also be odd smells and even smoke coming from replaced parts. All of these concerns should disappear within a day’s driving.
