Brake jobs are all the rage these days
A brake job is one of the vehicle maintenance tasks that is just outside most customers comfort zone. The idea of it can be a bit daunting. Having the right equipment and know how is the key. And why it is best to leave this type of work to the pros at the dealership.
To begin, lets review how brakes work.
When you press down on your brake pedal,fluid is sent from the master cylinder (the little white box under the hood) through brake fluid hoses down to the calipers.
With hydraulics, the brake fluid causes the caliper, which houses two brake pads, to squeeze against the rotor in each wheel, slowing it’s spinning. This action creates friction and slows you down. Some vehicles have drum brakes in the rear. When the brake pedal is pushed, a piston pushes the brakes shoes against the drum.
Through use, the friction material on the brake pads and the surface of the rotor wear down, get dirty and rusty. Parts need to be cleaned, replaced and readjusted.
Each time your car brakes are used, the brake pad material wears down gradually. That means your brake pads should be periodically inspected (which is part of the scheduled maintenance) and replaced as necessary. If you fail to replace the brake pads before the friction material is completely worn away, then direct metal to metal contact can occur, damaging your brake rotors and resulting in a much more expensive brake job.
Your vehicles brakes will often tell you when it is time for brake repair.
Brake problem symptoms are not only heard, but felt. The only way to get that is with a road test before any work is started. Always insist on taking a road test before work begins. Once up in the air, the technician can check the pads, shoes, rotors, drums, hoses, calipers and wheel cylinders.
With corrections made and work finished in the bay, another road test is in order to make sure all is adjusted and calibrated right.
