hmmm ihad a braking problem recently i pushed on the brakes they went right to the floor but did break about mid way but would creep down i checked the pads shoes and cylinders an bled the but still they did it, i thought it was a servo but i bought a servo was about to change it about 2 weeks after it started and it stopped and never did it again
it could be a leak on i pipe or maybe wheel cylinder, the right caliper might be nackered
