Mark offers excellent prices and repairs for all sorts of bikes and if you live in the direction of Kent (Orpington) specifically then you should check him out:
To replace hydraulic disk brake pads you will need:
- New brake pads – similar to the ones you are using before
- Pliers – to pull out the retaining pin
- Tyre lever or pad separator – to pry open tightly closed pistons
- Disk brake cleaner – if you feel the rotor needs cleaning
Background to the repair:
Hydraulic Disk Brake Pads are well known for needing little maintenance. The piston automatically moves in as the pads wear and therefore you don’t spend every other weekend tweaking them (damn you V-brakes!).
Pads need to be replaced once they reach 1mm or less or thickness. After that they’ll start to wear out the rotors.
This repair is useful for just doing an inspection of the pads and if they are worn then heading to the local bike shop to buy a replacement.
Disk brake Pad types
Two types of pad can be used for disk brake repair. Organic and sintered. Many pro-riders use one of each in the calliper to get both the benefits.
Organic pads will need some breaking in before any heavy riding. A couple of hard stops helps to get them working correctly. Sintered pads don’t need breaking in. They are hotter and somewhat heavier than organic pads but are ont appropriate in all disk brake systems. Whilst more effective, they do wear out the rotor more quickly than organic pads will.
Additional notes on the video:
Your disk brake design will vary slightly. Some pads for example are held in place using bolts instead of split pins. Also some disk brake pads are removed upwards instead of downwards. Be aware of this when following the instructions.
During the repair when the pads are out is a good opportunity to clean the calliper. Do so using an old toothbrush or a cotton swab.
