I've just got my hands on a copy of the Haynes Brakes technical manual. In the section on changing pads, it states (as has been said many times before) that simply pushing the pistons back into the calipers can damage components such as ABS sensors or the seals in the master cylinder. They suggest (lightly) clamping the flexible brake line and opening the bleed screw on the caliper so excess fluid can be drained off instead of being pushed back through the system.
I was just wondering if anyone does this or do you all just push the pistons back and hope for the best?
Also, given the common 7th gen problem of the rear flexible brake lines breaking down, does this seem like a sensible idea? I'm thinking that not clamping the line but just opening the bleed screw would be enough. What's everyone else's opinion?
