Fantastic DIY on brake renewal but..

When you push back the caliper back into the housing I was told to clamp the brake hose and open the brake bleed screw. This is so the excess fluid can be released out of the caliper and not back through the master cylinder as this can invert the rubber seals etc and cause damage. As a precautionary it's probably not advisable to force the fluid back to the reservoir.
