Question:  What are the signs that I need a brake job?

Express Car Care Answer:  Signs of brake problems often fall into one of two categories for Denver vehicles:  making noise or a pulsation in the brake pedal.  Why don’t we start with the noise.

Most brake pads have an audible brake wear indicator.  This is a small piece of metal that rubs on your brake rotor when the brake pads are worn to the point that they should be replaced.  The noise is a chirp or soft squeal.  This noise gives drivers enough warning to get their brakes serviced while there is still enough brake pad left to enable them to stop safely.

Any driver who ignores the chirp will find that the sound changes to a grinding noise.  This is more serious.  It means that the friction material on your brake pad is worn away and metal parts of the brake are grinding against the rotor when you press on the brakes.  Obviously, this metal-on-metal means that your brakes aren’t going to stop very well.  It also means that your rotor is being damaged.  It may need to be resurfaced or even replaced if it reaches this point.

Pedal pulsation is another noticeable sound.  When your rotor is not in perfect alignment, it pushes against the brake pads unevenly as you apply the brakes.  There could be a number of reasons for this, the rotor and wheel hub may not be mating well which causes the rotor to spin out of vertical alignment.  This misalignment can be caused by either the rotor or the hub, or a combination of the two.  If this persists, the rotor may even start to wear unevenly to the point that its thickness varies, causing an even more noticeable pulsation.  This uneven mating of the brake pad and the rotor when braking means less contact and a reduced braking power.

Your service center or the team at Express Car Care can determine the cause of the misalignment and remedy the problem.  Either unusual brake noise or pedal pulsation are signs for drivers that they have brake problems.  Drivers should have a tech check their brakes thoroughly and recommend any steps necessary to correct the problem.  A regular brake inspection is on every vehicles recommended list.  Ask your service adviser if it’s time for that very important brake inspection.
