Stripping the brakes

The mechanics of how disc brakes are dismantled and subsequently rebuilt are fairly straightforward. The way the system is put together is not complicated and, as long as each stage is carried out in the correct order, the job will progress smoothly.

The copper brake pipes here are going to be replaced but, if the brake pipes are being retained, it is a good idea to seal off the open end when it is unscrewed from the caliper. This means that only minimal brake bleeding will need to be carried out at the end of the job, rather than having to expel air from the complete system if all brake fluid has been allowed to drain off.

The male end fitting of the brake pipe can be easily sealed using an old female end fitted with a short piece of copper brake pipe whose end has been squeezed closed (similarly, use an old male end for open female ends, as on the front brakes on many models). It’s important to prevent dirt or rust getting into the open connectors of pipes and calipers if these items are to be re-used.
