When to replace brake rotors-Advance Auto Parts?
Like dished rotors, deep grooves are a problem because they don’t provide your pads a smooth, flat contact area, and this reduces your braking performance. 3. Bluing and hot spots. Your rotors get hot. If they aren’t able to properly dissipate heat, your rotors may be left with a blue ring or spots.
Is it easy to remove rear brake rotors?
Just FYI. The rear brake rotors are a bit more difficult to remove because behind the rotor’s hat are the parking brake shoes. You will most likely need to adjust them down to remove the rotor. Here are the directions for removal and replacement of the parking brake shoes.
Why do brake pads and rotors have to be matched?
Brake pads and rotors have to be “matched sets” when it comes to the materials. From the sound of it, the old pads (probably the cheap “value pads”) don’t match the new rotor material and quickly exceeded the operating temp of the pads and left uneven deposits of pad material on the rotor.
What to do if your brakes pulsate after rotor and pad?
Check all installs with a dial indicator for runout. Spin the rotor with indicator at 90 degrees on the rotor face near the outer edge. Runout should be zero, must be under .004″, the less the better. Clean pad back, piston, and caliper. Replace shims. Proper and complete lubrication of all metal-to-metal contact points.
Do you need to break in your brake rotors?
Average rating from 96 customers who received a Brake safety Inspection. Having new brake pads and rotors installed happens on a regular basis. Once those brake pads and rotors are mounted, it is essential to properly break them in. Bedding in, commonly known as breaking in, new brake pads and rotors is necessary for new brakes to work properly.
What causes brake noise after new rotors and pads?
One of the major cause of brakes noise after new pads and rotors is having excess brake dust that is trapped between the caliper and the rotor.

What does it mean to resurface brake rotors?
Resurfacing rotors, also known as machining or turning rotors, is performed by a mechanic who shaves a thin amount of metal off of each side. This made good economic sense in the past because rotors were more expensive and often thicker.
Why are my brake rotors shaped like a dish?
1 . Dishing. As the name implies, rotors can wear unevenly in such a way that they become shaped like a dish. This is generally undetectable at a glance, although you might feel a lip on the outer edge of your rotor.
Why do brake rotors get hot while braking?
Bluing and hot spots. Your rotors get hot. If they aren’t able to properly dissipate heat, your rotors may be left with a blue ring or spots. This condition might lead to a cracked rotor, but also the hot spots could be felt by drivers as a pulsation while braking.
