I've got a slight problem with my brakes at the moment. I've got Goodrdidge hoses, uprated fluid and recently swapped to Pagid Blue (fast road) pads with Ralliart anti-squeal shims. My discs warped and have had 1 skim and seem to be alright at the moment. My problem is - most of the time I get good feel from the brake pedal, quite firm - stops very nicely. Occasionally - say every 4th or 5th time I go for the brakes the pedal is very vague and goes down a lot further than normal. Seems to stop OK, it's just disconcerting when you're approaching a corner and it doesn't do what you expect. This isn't a fade problem as it doesn't just happen during periods of sustained heavy braking - it could be going to work, approach roundabout - soft pedal. The brakes have been stripped downa couple of time and everything look's OK, the next step is to go back to the original anti-squeal shims from the Brembo pads, but anyone any other ideas?
