Mike_Mac Posted May 26, 2008 Share Posted May 26, 2008 I'm in the middle of refurbing a full set of UK brakes prior to swapping them with my existing J-specs. I know you can either cut or remove the existing J-Spec front dust shields, but I was wondering if it's just as simple to fit UK dust shields instead, as I'd prefer to use the right kit from the outset rather than angle grinding the old. Is this a case of unbolting old and attaching new, or is it more involved than that. Also does anyone know of any UK ones that are available?

Steve Posted May 26, 2008 Share Posted May 26, 2008 I beleive most people cut them off because otherwise you have to remove the hubs to get the shield off. Link to comment Share on other sites More sharing options...

garethr Posted May 26, 2008 Share Posted May 26, 2008 I believe most people cut them off because otherwise you have to remove the hubs to get the shield off.Then, if you want to fit new UK shields, you can cut out a section and fit them over the hub.

Chris Wilson Posted May 26, 2008 Share Posted May 26, 2008 Fronts are easy, as stated, the rears also hold the handbrake shoe assembly, changing those is a much bigger job, I'd just (neatly) angle grind the rear ones off. Link to comment Share on other sites More sharing options...

Mike_Mac Posted May 27, 2008 Author Share Posted May 27, 2008 Does anyone have the part numbers for the rear shields please? And the fronts - I don't fancy trying to explain to Mr T what a dust shield is - I'd probably end up with anything from a hub to a brake disc! Thanks for the all the answers guys - I take it you'd need a press to get the hubs off? If so then grinding the UK shields to get them on seems the better option!

SUPRASUZUKI Posted May 27, 2008 Share Posted May 27, 2008 You can trim the shield arround the caliper mounting points with tin snips, then just bend the shield back a few mm to clear the bigger discs. Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 27, 2008 Share Posted May 27, 2008 You will almost certainly end up replacing both front hub bearings when you try to remove the hubs, for which a big puller or a press is needed. i'd just trim the the J-Spec ones unless you thrive on hassle and expense Link to comment Share on other sites More sharing options...
Mike_Mac Posted May 27, 2008 Author Share Posted May 27, 2008 I'd just trim the the J-Spec ones unless you thrive on hassle and expense You do remember my Supra don't you? Wouldn't the option given above of sliding the UK shields on by trimmng a section out work without having to remove the hubs? If it did then does the UK shield make a notable difference over the modified J-Spec, because if it's of little impact then I'll save the hassle and trim the J-Spec ones. (Enough hassle and expense inbound with replacing the suspension arms! ) Link to comment Share on other sites More sharing options...
wile e coyote Posted May 27, 2008 Share Posted May 27, 2008 I just cut the outer rim off so still got a dust shield of sorts. Link to comment Share on other sites More sharing options...

Chris Wilson Posted May 27, 2008 Share Posted May 27, 2008 Do what wile e coyote suggests, it's quick easy, and very neat if you have a steady hand with a slitting disc on an angle grinder. Link to comment Share on other sites More sharing options...

Gordon F Posted June 13, 2008 Share Posted June 13, 2008 Does anyone have the part numbers for the rear shields please? As far as I can remember, you dont need them. The UK rear brakes will fit over the Jspec rear shields. I only ever remember cutting off the fronts when fitting the UK brakes to my GZ. Link to comment Share on other sites More sharing options...

Kev.O Posted December 22, 2008 Share Posted December 22, 2008 Does anyone have any suggestions on how to remove the four bolts that hold the front dust shield on, without removing the hubs? My socket and ratchet are too big. A normal spanner will simply slip off as these b*ggers are tight. TIA Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 22, 2008 Share Posted December 22, 2008 A single hex ring or combination open ended / ring spanner will undo them easily. I have never had trouble undoing them with a normal bi-hex ring or combination though, either. If you're paranoid, apply heat before undoing them. If you knacker them grind them off, but they'll undo with a decent spanner. Link to comment Share on other sites More sharing options...

If I grind them off or snap one, how do I manage to re-thread the hole as the hub will be slightly in the way. Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 22, 2008 Share Posted December 22, 2008 I am assuming you are just binning the water shield and won't be fitting a bigger UK type. Don't grind them off (obviously) if you intend to fit a new one You'll get better brake cooling without a shield *UNLESS* you make up a proper ducted one and feed it with pressurised cold air Link to comment Share on other sites More sharing options...
