Where do I start?! Brake pads warning indicator (indicated from front left) came on recently and I had an advisory for rear brake pads at the last MOT. Along with these I had an ABS/Traction control fault, at first it was intermittent and then indicators where on permanently. A bit of research showed that the wheel speed sensors are usually to blame. So being fairly mechanical minded I thought I'd have a crack at the lot, I ordered Brembo discs and pads for the front and rear and an aftermarket sensor. I also bought a caliper winding tool (ebay special). Front pads and discs changed with no problems at all yesterday, came to undo the locking bolt on one of the rears and it's rounded off, tried hammering it on but kept slipping. So today took it to a local garage who managed to get it off with a windy gun. Cost me a couple of quid, result! Then onto the rear discs and pads, left rear wheel off, sensor changed, caliper removed and can't remove the carrier for the pads as I haven't got the right sized torx socket, I had one that was too big and one that was too small, very annoyed at this point. So I thought I'll just change the pads as the discs were still usable, only problem being, the caliper piston will not wind back, it winds out and slightly back in but will not go in even most of the way. Everything I tried didn't work. Extremely annoyed at this point! Right, old pads back in, only the piston won't retract anymore and there was no way of getting the caliper back on, so I left one pad out (cowboy I know) and stuck all back together and drove it down the road to a local garage and left it there. Brakes didn't feel right at all and went slightly spongy at times, I hadn't broken into the brake lines at this point so hopefully it's just because of me being gash. On the drive there the ABS/Traction lights flashed up again so the sensor didn't solve it, could be the loom or the ABS ECU which would be expensive! The garage will be looking at it tomorrow so hopefully the brakes get sorted as I need the car for Thursday to drive home on leave...... feeling pretty gutted tbh. Sorry about the epic post.
