3 Answers. Simply put a bigger rotor provided better braking, and a four pot caliper provides better braking - better meaning more, and more control (Everything else being equal). For the same force between the disc and pads, a bigger rotor generates more torque on the wheel - i.e. more stopping force.

Likewise, people ask, are thicker rotors better?

Thicker fins allows the manufacturer to produce a less expensive rotor because the surface that does all the stopping, the machined surfaces, can be made thinner but the replacement will still have the same discard thickness as the OE rotor even though the life expectancy can be severely shortened.

Beside above, can I put bigger rotors on my car? The point of having larger rotors is to have larger calipers to hold larger brake pads for more braking power. Just installing larger rotors won't do anything for performance and you may have clearance issues with the smaller caliper brackets, not to mention out of spec rotor wear that might cause braking issues.

Just so, do bigger brakes stop a car faster?

A big brake kit will not increase the stopping power of a vehicle or decrease its stopping distance due to the physics involved. A larger brake pad will only spread out the clamping force of the brake caliper over a greater area.

Why are my front rotors so big?

The front rotor is bigger because you CAN brake more with the front before losing traction. The rear rotor is smaller because a whole lot of extra braking force is just going to make the wheel lock up anyway, so a bigger rotor would just be a waste.

What happens if brake rotors are too thin?

When a rotor is too thin, it overheats and warps, leading to an annoying vibration or pedal pulsation. When rotors were thicker, they could take the wear from the brake pads, be machined and still have enough metal left to dissipate the heat.

How thick do rotors need to be to pass inspection?

One of the requirements for the state inspection is that the brake pads must be more than 2/32 of an inch thick. In addition to the brake pad thickness, the rotor thickness is checked out.

Can you put new pads on old rotors?

When a set of pads is worn out and need to be replaced, it is perfectly ok to install a new set of pads on the old rotors. The fact that a layer from the old pads has “contaminated” the surface of the rotor means little once the new pads are bed in.

How do you know if your rotors are too thin?

Signs that Your Brake Rotors Need to Be Replaced
  1. Shaking When You Brake. If the car shakes every time you brake, it could be a sign of failing rotors.
  2. Noisy Brakes. Though sounds don't always accompany bad rotors, a squealing or squeaking sound could be a sign of a bad rotor.
  3. Grooves and Score Marks on the Rotors.
  4. Rotor Is Too Thin.

How do I stop my rotors from warping?

Pro Tips To Avoid Warped Brake Rotors
  1. Here are some things to consider that will help prevent warped rotors:
  2. Upgrade to cross drilled rotors or cross drilled & slotted rotors.
  3. Cross drilled rotors and cross drilled and slotted rotors will provide better heat ventilation.
  4. When you change new brake pads make sure to take the time to do the proper break in.

Are drilled rotors worth it?

Pros: If you live in an area that experiences a lot of rain, drilled rotors are a very good choice. They perform well in rainy climates by offering a good “wet bite,” hold up well over the life of the rotors, and deliver more friction and more bite than their slotted counterparts.

How long should Brembo brake pads last?

Super Moderator. The mileage on your Brembo pads depends on the type of driving that you do. A lot of stop and go driving or hard braking will make the pads wear out faster. Under normal conditions, the front pads should last about 35,000 miles.

Why do cars have bigger brakes in the front?

It's due to physics - when decelerating the weight and energy transfers to the front of the vehicle, as a result front brakes are larger since they have more energy to cope with, and that extra weight also gives the front wheels extra grip and thus more braking ability.

Should you paint brake calipers?


If you are replacing the calipers as part of a brake job, this is a good time to paint them, while they're off the car. Brushing on the paint can help avoid that, but there's a risk of leaving brush marks. And you probably won't be able to reach every nook and cranny if you paint the calipers in place.

What comes in a brake kit?

A performance brake kit includes high-quality pads, rotors and calipers, which provide you with consistent braking power and less brake fade overtime. Not only does a new brake kit produce more friction, but it also dissipates heat more quickly, improving your overall braking performance.

Do I need to bleed my brakes after changing pads and rotors?

YES, the brakes should always be “bled” whenever pads and/or discs are changed. In this instance “bleeding” means the removal from the system of some old brake fluid. It does not necessarily mean replacement of all the fluid in the system.

Do all rotors fit any car?


Brake Rotors:
They can generally be used with any car, as long as the size of the mount is correct. So, when looking for a new brake rotor, match the attachment piece of your old one with your potential purchase. The components of the replacement brake rotor should also be fitted the same way as the original rotor.

How does rotor size affect braking?

3 Answers. Simply put a bigger rotor provided better braking, and a four pot caliper provides better braking - better meaning more, and more control (Everything else being equal). For the same force between the disc and pads, a bigger rotor generates more torque on the wheel - i.e. more stopping force.

Can you put any caliper on any car?

There is a very large misconception that any caliper can be used on any vehicle, as long as it can be made to physically bolt up in some manner. It is also possible that the pistons move completely past the seals in the caliper, resulting in complete and catastrophic brake failure.
