Johnboy_72 · Mar 4, 2019

My 1466 is blowing out the seals on the
piston for my brakes this started to
happen shortly after I replace the disc
brakes the problem is to much pressure.
Wear do I start to look to fix this
problem any help would be appreciated
thanks

sounds more like your housing is worn and the disc's are shot allowing the piston to come out to far. If the spacer plate discs and housing wear to much the piston travel will come to far out and leak by the o-ring seal. Would take quite a bit of wear but could happen. If that is not worn that much you may have a scratch/groove in either the bore or piston surface causing it to leak when it gets that far out. The Piston on the brake is only about 3/4 of an inch thick.
I don't think the pressure is adjustable except for the amount of pressure you put on the pedal.
