How to mess up a brake disc with a wishbone - by edhorne

[edhorne]

So

Suspension all shotblasted and painted and all back together. New balljoints etc. Quick blast up to the local MOT place only to find a big score on the inside of the offside front disc

A combination of the new balljoint protruding from the wishbone and the negative camber of the upright, post rebuild, had conspired to allow the disc to contact the edge of the balljoint. Thankfully only on full lock to the right.

Its rather annoying, as after the MOT it was going straight to Neil Garner for a full suspension geometry set up.

To avoid any further damage to the disc, I ground the balljoint back witgrinder and set a crazy positive camber and off we went to Neil Garner's (only a few miles away thankfully).

Looks like I took rather to much off with the grinder as I now have a crack in the wishbone. Arse

You live and learn (to check that discs have clearance after rebuilding suspension!)

Ed - If you can drive to Didcot, I have a wishbone there that you can borrow on a permanent basis.

Yep, I had exactly this same problem.

Quite thought I'd posted about it, but I guess I may have been sulking too much to actually get around to doing it.

Feel for you, I know how annoying it is, I've left the disks as it hasn't had a huge effect on braking.

Alan

thanks very much for the kind offer.

I hopefully have one on its way from Racing Green.

If there's a snag I'll be in touch.

All the best
