I am replacing the front 4 pot Wilwood calipers and disks on my V8. The pads rattle as the old design calipers have no springs to hold the pads, and the disks are uneven, so judder a little.
The notes I got with the car suggest that the disks are "vented escort" but Rally design thought that in the pictures they looked like capri 2.8 245mm x 20 as they mount on the back of the hub. The car was built in 1998. Would anyone have any idea please, or know how I can tell exactly what they are? The new design Wilwood calipers are supposed to be virtually a direct replacement (just a slight bracket mod with a file) but I have never changed disks before....any idea how they come off, and what needs to come off first please?
Why are you replacing the willwoods ? Anyway , calipers off first , just two bolts , piece of piss . Take the bearing cap off , remove the split pin and castle nut then the hole bearing/hub/disc assembly will slide off. Stick the disc in a vice with some alloy plates then simply undo the four bolts holding the disc to the bearing . REASSEMBLY is simply a reverse of this but put a little thread lock on the bolts.
The disc will be 247mm if it's Escort , just measure them . Don't change them before this Saturday though !!! (goodwood?)

That's brilliant - thanks Rob. A great description that will save me ages....after Saturday!!! There are several people with at least a couple of Stylus cars coming to cheer you on. There are a couple of friends in Caterhams coming, but we promised to go slowly for them. My calipers need changing because the old design (even with brand new pads) allows the pads to rattle to the point of embarassment over even a slightly bumpy road. The disks definately need a change, so thought I'd sort the whole lot together.
See you on Saturday. Hopefully with my new vinyl hood almost completed. Regards, Paul.
Didn't need the hood on Saturday....or on Sunday. Thanks for the advice Rob...I used my brakes a lot this weekend - covered several hundred miles going to Goodwood and back Saturday and Sunday via Stonehenge I think!! Having given them some harsh treatment, they are a lot better, pull a tad to the right, and still judder a little - but nothing like before. I measured the disks yesterday, and they are vented Capri 245 x 20. I tightened one wheel bearing and noticed that the disk wasn't quite true. I tried taking up the bearing, but in one position, the wheel would turn, and in another, it wouldn't due to the disk binding rather than the bearing being tight. Is this normal? Please excuse ignorance
I have heard that disks not running true can be due to several things including dirt on the mounting faces. How true do they need to be? Does the binding just on one side of the disk mean that the calipers are not properly cetralized on the disk?
Really enjoyed Saturday. I am going to have to have a go next season - more for fun than as a serious competitor though as I don't have the skill or the bottle.

More likely to be the uneven mounting of the caliper than bad mounted disc. I bolted the calipers on then measured the gap each side and washered accordingly.(some filing of washers too)
