Hi all these have been spoken about on many occasions and some people remove them completely but i wanted to keep them and refurbish them.Ive had no luck what so ever in finding a seal kit for them so decided to open them up and have a look.
this is one before
Very rusty and seized up so unable to bleed rear brakes.
and one after,stripped,blasted and laid out in order for you all to see the insides.They are very simple in design and the only reason i could see for them being seized was lack of good brake fluid(black and shitty) once cleaned and inspected i couldn't find anything wrong with the piston seal and main seal and will just replace the o-ring where it splits.I have removed the ABS but want to keep the valves for brake bias so will now rebuild and paint them.
