Are mountain bike disc brakes Universal?

Not all mountain bikes use disc brake platforms – however most modern full suspension and hardtail bikes will use a hydraulically activated disc brake system. … Disc brakes can be fitted to any mountain bike so long as the bike is equipped with two things: Hubs that have the fittings for a disc rotor.

Are bike disc brakes interchangeable?

As long as they’re the same size, I.E. 160mm/180mm/200mm rotors, you can swap them between brakesets indiscriminately. The real issue is the mounting type of the rotor.

Are brake discs universal?

Brake rotors are not fully universal and interchangeable, but they can be considered slightly more versatile than the brake pads that were discussed previously. They can generally be used with any car, as long as the size of the mount is correct.

Are disc brakes interchangeable?

Generally, disk brake rotors of same diameter are thought of as cross-compatible, but there are some edge cases when this might not be true: Rotor thickness might not be the same across manufacturers and disk brake calipers might be designed with thicker/thinner rotor in mind.

Are all disc brakes the same size?

Disc 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.

Are all mountain bike brake calipers interchangeable?

It’s best to use the same brand rotor and calipers. Some company like Magura would advice against using their brake and caliper with the rotors of different brand. They claim their calipers and pad as well as the rotor thickness are specially design to work together, it’s an automatic void of warranty.

Can I use any rotor with disc brakes?

You can use any rotor you like with any brake, within reason. Some rotors have narrower brake tracks than others, i.e. Shimano, but generally, it’s just a metal disk.

How do I find out what size my brake discs are?


  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.

How do I know which brake discs to buy?

The best way to ensure you get the correct brake discs is to check the diameter of the brake discs already fitted. The diameter and thickness of the disc is illustrated below. To measure the diameter you may not have to remove the wheel, however it would make the measuring process easier.

Are front and rear disc brakes interchangeable?

Front brake calipers work significantly harder than the rear, which requires them to be a different size to handle the force that is applied to them. … The front and rear brake pads cannot be interchanged, as the front pads will not fit on the calipers of the rear and vice-versa.

Are front and rear disc brakes the same?

Answer: Rear disc brakes are basically the same thing as front-wheel disc brakes. … They consist of three main parts: brake pads, a caliper, and a rotor. Brake pads are located on each side of the rotor and are actually pushed against the rotor to stop the wheel and thereby stop your vehicle.

Are Shimano brakes interchangeable?

Shimano brakes are very cross compatible, yes you can just fit better levers to your calipers.

How do I know if my bike disc brakes need replacing?

You should replace your pads when there’s 1.5mm or less of braking material remaining. If the pads are okay, replace the wheel and keep riding.

Are bike brake calipers Universal?

Each caliper is designed to take a specific size of rotor, in terms of both diameter and thickness. Whereas you can generally vary the diameter size of the rotors with the use of adaptors, different manufacturers and brake models will use marginally thicker or thinner rotors.

How do you measure bike disc brakes?

Rotor size is measured by diameter, ie. edge to edge through the centre. The size may also be etched on to the rotor which would be more accurate than measuring yourself. There are a number of common IS (International Standard) sizes of rotor from 140mm through to 203mm.
