A couple of weeks ago I noticed the nearside rear brake backplate looked a bit damp. The rear discs didn't look brilliant and I knew it was getting close to needing pads on the back too so ordered a couple of rear discs and an axle oil seal (I already had the pads). Finally found time to do it today. I somehow doubt my nearside rear brake was doing much......
At least everything came undone easily enough though, unlike the other side which hasn't been doused in axle oil. One of the caliper slider pins was seized solid but rather than trying to twist it out and shearing it off as I have done in the past, I decided to get a bit more technical. I drilled a 5mm hole in the caliper carrier behind the pin and tapped it with an M6 thread. Then I filled it with Plus Gas and left it to soak for a while. Screwed an M6 bolt into my tapped hole and it pushed the pin out easily. Once I'd cleaned everything up, I just cut the bolt down and screwed it into my hole to stop any crud getting in there.
