Common questions

How can you tell front and rear rotors?

How can you tell front and rear rotors?

Rotors are in contact with the pads at all time, you will feel the warped rotors. When braking you’ll get a pulsation in the steering wheel and pedal if it’s the front. If its the rear you’ll feel it in your butt.

How to check the thickness of brake rotors?

When checking brake rotor thickness, measure rotor in about 10 different spots, mark each spot to keep track of where you have measured. If rotor does not meet minimum thickness then replace, remember to always replace brake rotors in pairs. If your brake rotor passes thickness but you have a pulsation while using brakes, replace brake rotors.

How big is the front rotor on a Mini Cooper?

Jared Fenton Type and Year Min Thickness Front Vented Rotor, MINI Cooper R50/R52 20.4mm Front Vented Rotor, MINI Cooper S R52/R5 20.4mm Rear Solid Rotor, MINI Cooper R50/R52 (2 8.4mm Rear Solid Rotor, MINI Cooper S R52/R53 8.4mm

What should the rotor thickness be on a BMW E90?

Most factory rotors and some aftermarket rotors will have a minimum thickness stamped on the rotor. This will be in area of hat or hub flange. Clean rust away from rotor to uncover specs. Lift axle of vehicle you are measuring brake rotors on.

How do you know if you need new rotors?

Use a micrometer at the thinnest point on the surface of the rotor where it meets the pads to measure the minimum operational thickness. If your rotor needs to be cut or has worn passed this thickness, you’ll need new rotors. You may also discover your rotor has Disc Thickness Variation.

Where do you find the minimum operational thickness of rotors?

Engraved on the side of your rotor you can find the minimum operational thickness, within the veins of the rotor, or on the hat of the rotor. To accurately measure against the minimum thickness use a micrometer at the thinnest point on the surface of the rotor where it meets the pads.

When do you need to replace your brake rotors?

The strength of the rotor is also reduced, leading to more risks of cracking or not braking. Whenever you check the brake pads, it’s essential to check the rotor thickness as well. If its thickness is below the minimum specification and it cannot be resurfaced, then you need to replace the brake rotors immediately.

How can I check the thickness of my brake rotors?

The rotor thickness should be measured using a micrometer. The thickness should also be gauged before and after the rotors have been turned, to check for proper thickness or depth specification. 1. Raise the front or rear of the vehicle, depending on the rotors that need to be measured, and secure the vehicle with the jack stand.
