has anyone come across this before, I have a crack on the mating face were the cover washer sits on the brake hose union, its extends from here to the outer body of the calliper causing fluid to leak.
I noticed it today, riding along a fire road, apply my brakes, rear is squealing like made and not slowing me down but the lever felt normal, no extra travel or spongy. on inspection I found my chain stays, disc and pads had brake fluid on them which seemed to be coming from the union so I suspected I would just need some new washers, stripped it down to check and found said crack.
nothing has hit the brake pipe or union, the bolt has not been over tighten, last removed around 3 years ago when I fitted a new hose when changing frames, torqued to spec and brakes have been problem free since then
I have emailed hope, not very happy that I am going to have to fork out for a new calliper and pads, the calliper is £60 from crc. will see what they say, I always hear they have fantastic customer service. these brakes are well of the warranty and brought second hand.
pictures a little poor, found it had to get camera to focus on crack but you can just about see it
