I’ve just fitted a set of brand new SLX brakes. First ride out yesterday, and after an initial great start (lots of power, good modulation) on the second descent of the day the rear started to fade a bit (ie pulled back with no power, pumping the lever made it work ok) and by the last descent I pulled both brakes hard and they just pulled to the bar – nothing. Again fortunately pumping them got some power back and slowed me down.
I’m fairly heavy (around 85 kg) and I was cracking on (last descent was Gores in the Peak down to the reservoir if anyone knows it) but I wasn’t brake dragging much if at all.
Just in need of a bleed or something more sinister? I need to shorten the hoses so bleeding is no problem.
Running UberBike sintered pads if that makes any difference.
