Rotor replacement why

That is, keeping the brake engaged continuously as you drive. This can happen, for example, with drivers who have to navigate hilly terrain on a daily basis. The heat that caused such coloration may have also compromised your braking system. If you're questioning your brakes and wondering when to replace brake rotors, it's time for a free brake inspection at your local Tires Plus. During your brake check, we'll determine if your vehicle needs any further brake service or repair and if so, talk to you about next steps.

Your steering wheel vibrates — the sensation is also described as shuddering or pulsing — because the pads are following the contours of the warped rotors.

If your steering wheel is giving you vigorous handshakes, a rotor replacement may be in order. Here are some signs that you may need brake rotor replacement, along with tips on ruling this problem out:. Aside from the brake pedal pulsation one feels when the ABS engages, stepping on the brakes should not generate any other noise or vibration, that is, as long as brake rotor runout is less than a few thousandths of an inch.

Generally, brake rotor runout, over 0. Long braking downhill or riding the brake can easily deform a brake rotor, typically referred to as a warped brake rotor. Resurfacing or machining a warped brake rotor may solve the problem, but the uneven removal of material may actually cause it to warp again. In this case, brake rotor replacement may be the only permanent solution.

Rust scale and buildup on the wheel hub can keep the brake rotor from seating properly, mimicking a warped brake rotor. Clean all rust and grit from the hub and rotor mounting hole and try again. On many vehicles, this can easily deform the hub or rotor, leading to brake pulsation. Lift the vehicle, loosen the lug nuts and then use a torque wrench to force each fastener in the proper sequence.

Just like brake pads have a minimum thickness, brake rotors also have a minimum thickness. If the rotors have been machined more than once, double check that they are still above the minimum thickness.

These deposits are brake pad material that collects on the face of your brake rotors and creates uneven spots. Brake pad deposits occur due to several factors — including a brake system subject to excessive heat, incorrectly fitted pads, and uneven clamping due to seized brake pistons. When brake system components corrode, they tend to grind against each other — causing those loud brake noises.

The best way to prevent grinding noises is to pay attention to your brake wear indicator and replace your worn brake pads. Brake rotors are constantly subjected to heavy heat, which can cause their surfaces to crack. There are two types of cracks that can occur on rotors:. The second type of crack is a crack to the edge — and is an indication that the brake rotor is at the end of its life.

If you notice extensive damage or grooves on your brake rotor, it may be time to switch them out for a new rotor set. When your brake pads wear out heavily, the metal backing plate and rotors come into contact — damaging the rotor surface. You should also watch out for road debris, rust, and corrosion that can damage your brake rotors. Note: A grooved rotor is not the same as a warped rotor.

Ideally, take your car to a qualified technician so they can check and replace your brake rotors if needed. Wondering how much a brake rotor replacement will cost with RepairSmith?
