Anyone else have these? Just had them fitted, have done the usual bedding in and find the rear not as strong as I'd hoped. New 180 rotor - same size as before, clean. Not used any lube/oil etc to contaminate since fitted. Can pedal forwards with the lever fully on.

Front brake seems to be working fine so far. 1 ride so far.

Anything else to try before going back to the shop?

Mine are great. Must be a problem.

If you can pedal forward with the brake lever fully pulled then you either have air in the system (bleed required) or dodgy pads (contaminated).

The way it sounds i'd go with air in the system, probably in the cailper, so have a good bleed, rears are a pain these days due to being internal, old days you'd just remove it to get at any trapped air, now you need a bike stand and tweaking it a lot!
