Old pads were squealing, on inspection they were totally shot down to backing both ends – not sure how after about 6 hours riding but hey ho. Superstar sintered pads went in, and were howling like a banshee within 90 minutes. Stripped the brakes down, cleaned everything, completely cleaned pads & discs in hot water then iso and sanded everything. Bedded them in again and were OK for a big day last weekend, then towards the end of day 2 same again, no power and squealing. Cleaned again and today same thing, after 90 mins they’re terrible. Coming from both brakes. Back starts it first normally?
Looks like i’ll be going back to the shimano pads at £lots.
