Got everything ready to replace front discs and pads yesterday, removed pads, but was unable to shift the caliper bolts in order to replace disc.
No matter what I tried, it was not moving! Granted I could not get a breaker bar in the space, but I was concerned about the car moving off the axle stand and jack!
Any ideas?
Also, I plan on re-using the caliper bolts with thread-lock, is that ok or get new?
On a positive note, the wear on my EBC redstuff pads was only around 2mm having been on for in excess of 30k miles!

Thanks

I turn the wheels so I can get a breaker bar on. Just be careful with the stands (I always put the wheel I have off under the sill just in case)

i tried turning the disc/wheel but it would not move - The videos i've seen shows the disc being turned by hand. I'm assuming the key needs to be in the ignition with steering lock off then or do you jack up with wheels already turned?
Thanks

I think you will win in the end . You can seen them done on youtube but never see anyone use a torque wrench to set them after .

Finally done, some pics attached - Old Redstuff pads vs New ones - not much wear at all for 30k miles. Old discs have been on since I've had the car at least 40k miles.
The bolts were much easier with the breaker bar and 18mm socket.

Thanks all.

yep, on stands and jacks as well, it was just a case of getting it where the breaker bar just cracked the bolt, then just used ratchet drive.
I am, very soon, going to invest in a 24 volt rattle gun, i just do not seem to have the grunt these days to slacken off tight bolts.

I had a problem the other year with the caliper bolts , I drove the car onto wheel ramps first , used a breaker bar to loosen a turn , then took the car back off the ramps and put it on axle stands finishing off with a ratchet . I replaced a couple of the bolts where they had begun to round off

I think technique plays its part too. At work, when I work with a young apprentice, they try undoing stuff & fail dismally .... I think they try to just use their arms instead using a bit of weight too. Perhaps I just have a bit more weight to use than they have :rolleyes::rolleyes:
