314mm Brake Fitting - Any Tips?

[Thomas1]

I'm going to be fitting my recently acquired 314mm front brake disks, calipers and pads on the next dry-weather day when I'm not in the office. Does anyone have any (sensible!) tips/experiences they had when doing this on their car that they'd like to share? Ta.

Does anyone have any (sensible!)...

Aah, you want sensible replies in your own thread! You gotta practice what you preach then!

In reply, there's nothing too major really. The bolts that hold the carrier on are FFT, so you're likely to need a long breaker bar with an extra bit of tubing/scaffold pole type stuff. Not a whole scaffold pole but you get the idea.

Make sure you fit the new calipers the right way up. Seriously, they will fit the wrong way up (won't they plasma? lol) Bleed nipple needs to be at the bottom. The caliper/carrier bolts need cleaned of all the thread lock stuff and fresh applied.

Basically follow the How 2 that's on here for doing front discs and pads and all you're really doing extra/different is swapping the caliper/discs/carrier for different ones and bleeding the system - the rest is basically as per that How 2.

Oh, you'll also want to get new copper/brass washers for the brake hose connection - may as well start off with new ones.

Duncan the bleed nipple needs to be at the TOP to get the air out not the bottom

Other than that just as D said

Oh Gawd, I was getting myself mixed up 'cos I was thinking about what plasma did! lol He had them at the bottom which is why they wouldn't bleed.

Thanks for pointing out me typo.

Make sure the bolt you remove is a damn good fit into the socket, you might need a long bar too so you can break the seal, they arent tight, there $*&!£%!!!!! tight

dont forget to brake a few times when the new pads are fitted to get the caliper piston back into place

and give the new discs a wipe over with white spirits to remove the anti rust coating that there covered in

Cheers Gents.

Is there an echo around here?

Won't that leave a bit of a film/residue? I've always used brake cleaner as it completely evaporates away.

Damn, ive got your disease now, not reading the posts properly

As long as you wipe the discs hard enough itll fetch it off, and its cheaper than brake cleaner

Right. I've never tried it (white spirit) on discs (as I've got a 5l tin of brake cleaner that I got from a motor factors) but from using it on DIY etc. I thought it'd leave a slight residue. If it works then that's all that matters.
