Have been noticing an occasional build up of brake dust on the front passenger alloy, and yesterday my girlfriend rang me in panic as the wheel was very hot and and she could smell them burning after a short drive on the motorway. As we've only had the car a few months, this is the first time I've done any mechanical repairs to the car, so was wondering what tools are required to take the caliper slider pins out. Want to check and lubricate those before going down the caliper rebuild/replacement route.
