Replacing Brake Pads

Tools: Allen Keys
Parts: Replacement Brake Pads
Time: 20 Minutes
 


Brake pads can wear down extremely fast, especially in the harsh environment that MTBs are normally used. Because they can wear so quickly it's a good idea to check your brake pads before and after every ride for wear and misalignment. You can do serious damage to your rims if you continue to wear pads right down, not to mention the fact it could severely effect your braking. It's always a good idea to have a spare pair of pads lying around and it may be worth taking some with you on rides, in case they need replacing unexpectedly.

Because of the importance of efficient braking DO NOT attempt any maintenance on your brakes unless you are completely confident in your own ability.
 

Releasing The Retaining Clip1. Before you do anything, make sure you have the correct pads for your brakes. If you aren't sure, compare your old pads to the new ones before you buy them. Once you're sure you've got the correct replacement pads, release the brake arms by undoing the retaining clip from the cable housing.

Removing The Brake Blocks2. Remove the brake blocks by loosening the bolts on the end of the stems with an Allen key. Remember to place the new pads into the slots with the spacers in the correct order.
3. Before you put the new pads on, check them to see if there are any markings to indicate in which direction they are supposed to be mounted. Make sure they go on the right way round and then partially tighten the pads.

Dialling Back The Cable Adjuster On The Brake Lever4. Reattach the retaining clip to the cable housing and if needed, adjust the brake cable by loosening the cable clamp on the brake arm. Make sure the cable adjuster on the brake lever is dialled back to the lever. Once you've replaced the brake pads you can adjust this to determine how far back the brake levers go when the brakes are applied, but remember that this effects the cable length.

5. Now you need to adjust the brake pads so that there's no more than 3mm between the pads and the rim on either side. Make sure that the pads sit squarely on the rim when applied, but angle them so that the front of the pad is fractionally closer to the rim than the rear. Once you've done this, tighten the blocks fully. If one brake arm is closer to the wheel than the other, you need to adjust the spring preload, see Centring V-Brakes.
