I can't see any that halfords grease that is suitable for o rings & rubber seals if its lithim grease it WILL deteriorate your outer seal & you will start to see traces of brake fluid leaking down into the footwell area. Any grease even WD40 will stop the squeak but all will damage the seal.Peterbfd said:I used the Halfords stuff for half the price about 8 weeks ago and it has been silent since
