Brake Pads

What are Brake Pads and what is their main purpose?

Brake pads are the direct contact point between your brake and the rim. They consist of a metal core with a threaded bolt and an attached rubber block. The quality of the rubber determines braking power, modulation, and noise level.

What types of rubber compounds are there?

The color is not just design, but a code for hardness:

Clear / Transparent (Soft)

Very soft rubber compound. Offers extreme grip ("bite") on painted and anodized rims. Disadvantage: They wear out faster and tend to "squeak".

Black (Hard/Medium)

Classic compound. More durable and modulatable, but often with less absolute stopping power than clear pads. Good for chrome rims.

Colored (Red, White, etc.)

Usually medium hardness, similar to black pads.

Which brake pad fits my BMX?

Almost all modern BMX U-brakes use the same mounting standard:

• Threaded Bolt: The standard. The brake pad has a fixed bolt with a nut and washers for alignment.
• Shape: Look for a low-profile design if you ride wide tires to avoid clearance issues.

How do I install brake pads correctly?

Correct alignment is crucial to avoid squeaking:

1. Loosen the nut slightly so the pad can move.
2. Press the brake against the rim. The pad must sit centrally on the sidewall (not touching the tire!).
3. Toe-In Adjustment: Place a piece of cardboard under the rear of the pad before tightening. This way, the front of the pad hits the rim first. This prevents vibration and squeaking.
4. Tighten the nut.
