The primary function of the brake cup is to provide a seal between the master cylinder and the brake caliper. When the driver engages the brake pedal, the force is transferred through the hydraulic fluid, which creates pressure in the master cylinder. This pressure is then transmitted by the brake cup to the brake caliper, where it activates the brake pads, causing them to press against the brake rotor and ultimately slowing down or stopping the vehicle.

One of the key features of a brake cup is its ability to withstand high levels of hydraulic pressure without leaking. It is crucial to ensure that the seal is maintained under extreme conditions to prevent brake fluid loss, which could lead to a loss of braking power. Brake cups are manufactured using durable materials, such as rubber or silicon, which can withstand high temperatures and pressure fluctuations, ensuring the longevity and reliability of the brake system.

Brake Pads

Brake pads are a vital part of your braking system that can often be overlooked. To get the most out of your bike's brakes it is important to choose the right compound brake pads. Rider weight, trail conditions and the style of riding you like to do can all play a part in choosing the right pads. Below we have listed the pros and cons of the two main types of brake pads we stock but remember, this is only a guide as we understand that as mountain bikers we don't always ride in the exact same conditions every ride.

Organic/Resin Pads

Organic/Resin pads are made from an organic material bonded together with a resin.

Pros:

• Quick to bed in
• Great initial bite feel and modulation
• Less noise
• Don't heat up as much as metallic pads

Cons:

• Wear faster especially in wet/muddy conditions
• Less power at the higher end (High-speed DH & long braking)
• Can glaze over
• Best suited to lighter riders, XC and people who like a brake with plenty of initial bite.

Sintered/Metallic Pads

The sintered/metallic pads are made of hardened metallic ingredients that are heated and pressed together.

Pros:

• Will last longer than organic pads
• Can withstand high temperatures
• Great power at high-end braking (high-speed DH & long braking)

Cons:

• Hold a lot of heat which can overheat mineral oil brakes
• Take a long time to bed in
• Lack the initial bite of resin/organic pads
• Can be noisy

Sintered/metallic pads are great for heavier riders and DH/Enduro racers. They will provide long-lasting braking power and stand up to any conditions.

Disc Rotors - Size and Power

The size of your rotors will directly affect the braking power. It has been estimated that a 20mm larger rotor can give you up to 15% more stopping power. Larger rotors will take longer to heat up and dissipate heat faster.

Generally, XC bikes run a 140-160mm rotor and Trail/Enduro bikes run 160-180mm rotors although some EWS riders will run 200mm rotors up front, DH bikes will run 200mm rotors for maximum power. Selecting the right sized rotor can make all the difference!

Larger Rotor

Pros:

• More power
• Better heat dissipation

Cons:

• Less clearance on rocks, sticks etc.
• More prone to warping/bending

Smaller Rotor

Pros:

• Lightweight
• Better clearance
• Less prone to bending/warping

Cons:

• Easier to overheat on long descents
• Less power than larger rotors
