FAQs
Are these brake blocks suitable for all types of bikes?
These Clarks CP514 brake blocks are specifically designed for V-Type and Cantilever brakes with post mounts. They are not compatible with caliper brakes or other mounting systems.
How do I know when to replace my brake blocks?
Most brake blocks have a wear indicator line. If this line is no longer visible, or if the rubber appears significantly grooved, worn down, or hardened, it's time for replacement.
Can I use these on carbon rims?
These pads are generally intended for alloy rims. Using them on carbon rims may cause damage or premature wear to the rim. Always consult your rim manufacturer's recommendations.
What does 'post type' mean for brake pads?
Post type refers to the mounting system where the brake pad attaches to the brake arm via a threaded post, rather than being secured by a nut on the end of the pad's bolt.
How many brake blocks are included in a pair?
A pair includes two brake blocks, which is sufficient for one bicycle (covering both front and rear wheels).
What is the length of these brake blocks?
The Clarks CP514 brake blocks are 55mm in length.
Troubleshooting
Brakes are not stopping effectively.
Ensure the brake pads are correctly aligned with the rim and making firm contact. Check for wear on the pads and replace if necessary. Clean the rim surface and brake blocks of any debris.
Brake squeal or noise.
Slightly toe-in the brake pads (angle the front of the pad inward towards the rim) to reduce noise. Ensure the rim surface is clean and free from contaminants.
Brake pads wear out quickly.
Check that the rim surface is clean and free of embedded grit. Ensure the brake blocks are properly aligned and not dragging unnecessarily. Consider conditions; very abrasive conditions will naturally reduce pad life.

Setup, Compatibility & Care
Setup:
These brake blocks are designed for post-type V-brakes and Cantilever brakes. Ensure your brake arms have the appropriate posts for mounting. Loosen the retaining nut or bolt on your brake caliper, slide out the old brake block, insert the new 55mm Clarks CP514 block, and re-tighten the retaining nut. Adjust the brake pads to align correctly with the rim surface for optimal performance.
Compatibility:
- Brake Type: Compatible with V-Type and Cantilever brakes.
- Mounting: Requires post-type brake mounts.
- Rim Type: Designed for standard aluminum or painted alloy rims. Avoid use on carbon rims unless specified by the rim manufacturer.
Care:
Regularly inspect brake blocks for wear. Clean the brake blocks and rim surface with a damp cloth to remove dirt and debris that can degrade performance and accelerate wear. Replace brake blocks when the wear indicator line is reached or when the rubber becomes significantly grooved or hardened.
