I've known for a short while that my Rex is due for new pads at the rear. The recent good weather :sunny: and the fact that it's half term has put more mileage on the Rex than anticipated. :ups: Rear brake started squealing on Saturday and failed altogether today. One thing I have noticed and only just remembered about the rear brake on the Rex, (mine anyway) is that the pads don't wear evenly. When viewed from underneath, behind that black plastic cover my pads looked very close to their service limit. However, the edge nearest the wheel spindle was all but down to the metal backplate and one pad was more worn than the other. I'm guessing that the squealing was caused by one of the caliper pistons being just about at the end of its travel and not applying as much force to that side of the disc. I know that both pistons are operating as they should as it was by checking these that I discovered the state of the pads. Thankfully, no damage has occurred to the disc.
I know I probably use my rear brake a lot more than most and will shortly be on my 4th set of pads for this bike. Unlike some, I've never had any bother with seized pins but have been caught short of friction material in a similar way before. i.e. worn tapered pads. For those of you that either haven't had your Rex for as long, or covered as many miles as mine (27K) be aware of this potential problem area.

I recently followed the wise words posted here and stripped both front and rear calipers partly because my brakes were squealing on every application Front pads were almost worn to the limit and rears were glazed over and as GREMLIN said, very uneven in their wear I fitted EBC DOUBLE H SINTERED PADS 'C' COMPOUND both front and rear (they say you should not fit to the rears only, must be front & rear or just fronts). The brakes are far superior now with instant bite and the squeal has gone. I also copper greased the pistons and those pesky retaining pins, cleaned the calipers inside A very satisfying job

My rear ones have just gone on to the metel yesterday. Just off to buy some new ones & will fit them this afternoon... you make it sound so simple, my caliper was so f***ed that I have had to fit a spare and have to completely rebuild it, new seals and pins and pads are required, never again am I gonna neglect the rear brake. by the way is anyone knows of a cheap sourse of these I would be grateful

It wouldve been a piece of piss-a 5 minute job involving just a pair or pliers if it hadnt been for the moron that last fitted pads & omitted to grease one of the pins...the BASTARD... I wouldnt have believed the work involved in getting that f**king pin out. Needless to say,it was a good job i had a spare one to re-fit...WELL GREASED i hasten to add...!

It wouldve been a piece of piss-a 5 minute job involving just a pair or pliers 5 minutes?? It would only take me that long if that was to include 4 minutes searching for the pliers. A four year old with his Fisher Price toolkit could probably do better too. What I'm trying to say is that the job really is that simple if the rear caliper is properly maintained in the first place, which incidentally , also takes less than 5 minutes, with or without Fisher Price pliers. I'm sure I could actually remove rear pads from mine without using any tools at all.
