How do I know what size my brake discs are?

HOW TO MEASURE A BRAKE DISC

1. ID = Inside Diameter: Measure from inside edge to inside edge.
2. OD = Outside Diameter: Measure from outside edge to outside edge.
3. Measurement from inside edge of mounting hole to inside edge of bolt hole.
4. Bolt hole diameter: measure from inside edge of bolt hole to opposite inside edge.

Are all brake discs the same size?

Discs are available in different sizes. All other things being equal, a large disc will slow you down faster than a small disc. Shimano’s road disc brake system has been designed for use with 140mm or 160mm rotors, the idea being that users can choose the size to suit their weight and intended use.

Can I fit bigger brake discs to my car?

While you can achieve great things with the right upgrades to the brake system your vehicle came with, eventually you can exceed what even an uprated pad/disc/fluid combo can do. By going bigger, you give the pad and disc more surface area to work with.

Is a bigger brake disc better?

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.

What is the minimum thickness for brake discs?

37 mm
Providing continuous cracks are not apparent, minimum brake disc thickness is 37 mm. Brake discs should be replaced in pairs. Brake pads should also be replaced when new brake discs are fitted. If this instruction is not adhered to, there is a danger that braking performance could be seriously reduced.

How many miles do brake discs last?

Generally, brake discs should last more than 50,000 miles on average, but a number of factors affect the lifespan. If you keep them well maintained and drive sensibly, you may be able to get up to 80,000 miles out of one set!

What are the best brake discs to buy?

How thick should brake discs be?

All new brake discs are 45 mm thick. Providing continuous cracks are not apparent, minimum brake disc thickness is 37 mm. Brake discs should be replaced in pairs. Brake pads should also be replaced when new brake discs are fitted.

Are big brake kits worth it?

The common myth of a big brake kit is that your car will stop faster with larger pads and rotors because you have more surface area (thus more friction). The truth of the matter is that most likely, you already have more stopping friction in your stock brakes that you can use.

Why are rear brakes smaller?

Rear Brake Design — Stability As such, they don’t develop nearly as much heat as the front brakes. Smaller brake calipers also give less clamping force. Smaller brake pad surface and less aggressive brake pad material for decreased friction. Smaller diameter brake rotors for less stopping torque.

How can I increase my brake power?

Getting to the point, there are four ways to improve brake torque:

1. Increase disc radius. Larger discs will allow for more brake torque as the brake pad will apply pressure at a larger radius, allowing for a higher moment.
2. Increase caliper piston area.
3. Line pressure.
4. Friction coefficient between the pad and rotor.
