Disc Brakes

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

Hamilton Service Station Answer:
Signs of brake problems often fall into one of two categories for Portland : making noise or a pulsation in the brake pedal. Let's 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 they should be replaced. The noise is a chirp or soft squeal. This noise gives Portland drivers enough warning to get their brakes serviced while there is still enough brake pad left to enable you to stop safely.

Portland residents who ignore the chirp find that the sound changes to a grinding noise. That 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 stopping very well. It also means that your rotor is being damaged. It may need to be resurfaced or even replaced.

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, causing the rotor to be spinning 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 it will reduce braking power.

Your service center or the team at Hamilton Service Station in Portland can determine the cause of the misalignment and remedy the problem.

Either unusual brake noise or pedal pulsation are signs for Portland residents that there are brake problems. Portland drivers should have a tech at Hamilton Service Station check their brakes thoroughly and recommend any steps necessary to correct the issue.

A regular brake inspection is on every vehicle's recommended list. Ask your friendly and knowledgeable Hamilton Service Station service advisor if it's time for brake inspection.
