Changing caliper seals from DOT to Mineral compatible
Relatively new to the disc world, but I am upgrading the brakes on my disc roadie.
I'm changing the 2 piston calipers (TRP Dash) to Avid X0 Trail 4 potters.
Why, ? Because I can and I like to muck around.
As the Avids use DOT 5.1 and the TRP Parabox uses Mineral oil, I'm changing the caliper piston seals.
I am chasing down a couple of leads to get suitable piston seals, but if they don't work out, can anyone recommend alternative suppliers ?
The diameters in question are 14mm and 16mm
Good luck with that. Keep us posted.
Some leads have come to nix, but pretty sure that I'll manage to do it !!
Any help would be appreciated though
Done it !!!!!!
Conversion done and all good to a point.
Brake fluid and brake pads don't mix .... :roll:
The rears are fine, but the front still have a bit of contamination, but gradually clearing it up.
Short flat ride last night, first one for 3 weeks, so may get out again tonight to do some more bedding in.
So far so good, but took a bit of stuffing around with the bleeding to get it right.
Hose routing is great, so looking pretty good so far.
Went for a second ride last night, but this time with some hills. Got rid of some more contamination on the front pads, and they were much better, but in the end, I think there is still some contamination there. Picked up a set of sintered pads from the LBS (coz the resin ones were $7 more !! :?: ).
Anyway, the end result is ...... BRILLIANT :mrgreen:
The rear brakes work fantastic, and the front are 90%, but that's due to contamination. The modulation is great, as is the lever feel. Whilst it's early days, I am more than happy with it the end result.
