I have had trouble with my rocco's brakes for some time, I have replaced discs, pads, shoes, cylinders and thoroughly bled. My suspicions lead me to think the master cylinder needs replacing so I have just bought one to fit. When inspecting the master cylinder currently fitted I noticed each of the brake pipes coming from the bottom of the m/c have the following brake pressure regulators fitted, I would like to know a) whether these are standard and b) if not, why someone has fitted these and could this be the reason the application of brakes is poor i.e. my foot is at the floor before the brakes slightly engage!
Thanks
