fullthrottle Posted May 11, 2015 Share Posted May 11, 2015 I have just converted my 1977 Spitfire 1500 to the Canleys Trunnionless suspension and at the same time renewed the front wheel bearings. Now I am finding that the brake disc is fouling the outer inside edge of the brake caliper on the drivers side. I am struggling to work out what is wrong. I am pretty sure everything is fitted correctly, and I have re checked that the bearings are seated properly. Any suggestions? Could it be a bent stub axle perhaps?

WIMPUS Posted May 11, 2015 Share Posted May 11, 2015 Did you fit a new felt seal also when you changed the bearing ? As i heard the new ones are to thick or something.That would be probably your problem :) Quote Link to comment Share on other sites More sharing options...
john2502 Posted May 12, 2015 Share Posted May 12, 2015 As Wim says felt seal would be the first thing I'd investigate, If replaced, like mine i assume it would have been a load thicker than the one you took out of course. Quote Link to comment Share on other sites More sharing options...
Martin M Posted May 12, 2015 Share Posted May 12, 2015 felt seal mounted in the correct direction? Martin Quote Link to comment Share on other sites More sharing options...
fullthrottle Posted May 12, 2015 Author Share Posted May 12, 2015 Thanks for your responses guys, I will investigate the felt seal this evening. It was a good deal thicker than the one I took out, though I assumed that the old one had just squashed or worn down over time. As to whether it is the right way round, I'm not sure as the metal part of the seal on the replacement was much thinner and I could not fit it into the hub, so I used the metal part from the old seals with the new felt. The metal part is definitely on the bearing side, I didn't expect there to be a right and wrong way for the felt, so that could be the opposite way round. I will try both ways for the felt, try again with the new metal parts, and if all fails try the old felt seals. I will let you know how I get on.Andy Quote Link to comment Share on other sites More sharing options...
DickyM Posted May 12, 2015 Share Posted May 12, 2015 Hi FullThrottle,I have just recently upgraded to the same VL as well.Curiously I had a similar problem but ended up solving it by re-balancing the bearing and pressing the pistons out of the calipers and refurbishing them cleaning all the grunge out. Admittedly this is a setup with alloy front hubs and beefed up stub axles so slightly different.Are you sure its not just the bearing end float is out. As people have said is the felt seal cap replaced the right way round (as you used the original one) and nipped the bearings up correctly?Good luck,Dicky Quote Link to comment Share on other sites More sharing options...

Going by the photo this one is hitting the calliper housing rather than the pistons; I’d agree with all those who have posted that the felt seal is stopping the hub from seating fully.

Dannyb Posted May 12, 2015 Share Posted May 12, 2015 The new felt on these bearings are twice the thickness of the original. Either replace the old felt or cut with sharp blade around it's circumference of the new one. Quote Link to comment Share on other sites More sharing options...
DickyM Posted May 12, 2015 Share Posted May 12, 2015 Entirely right Paudman - now I've looked at the picture properly that was an oversight... more haste less speed!490 wrote:Going by the photo this one is hitting the calliper housing rather than the pistons; I’d agree with all those who have posted that the felt seal is stopping the hub from seating fully.

Pete Lewis Posted May 12, 2015 Share Posted May 12, 2015 the metal retainer must be fitted with recess outwards so the felt sits inside it contained by the rim on the ring so the felt sits partly inside the hub bore , so felt | ] >< nut not | [ >< nutif that makes any help.Pete Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted May 12, 2015 Share Posted May 12, 2015 Only 3 options as far as I can see....1. Hub sitting too far out-board relative to upright. Which would suggest something (eg. felt seal as suggested above) behind the hub preventing it going fully home on the stub-axle.2. Caliper too far inboard - something between the caliper and the up-right that shouldn't be there? (Splash/dist shields?)3. Relative position of hub and caliper wrong... upright not the right shape/size. I wouldn't think that was a valid option.Regards,Sam Quote Link to comment Share on other sites More sharing options...
sparkytph Posted May 12, 2015 Share Posted May 12, 2015 I had same problem after I removed the splash shields ended up putting in a spacer washer to move the caliper back to original position Quote Link to comment Share on other sites More sharing options...
fullthrottle Posted May 13, 2015 Author Share Posted May 13, 2015 Hi Guys,Unfortunately the felt seal did not make any difference. I was thinking of replacing the stub axles anyway, so that is what I am going to do. Prior to replacing the bearings and the carriers the caliper was a lot closer to the inside of the caliper, so if I have refitted the stub axle 180 degrees out from original, then it would make sense that the disc would be closer to the opposite side of the caliper. I'll let you know what happens once I have replaced the axles.Thanks,Andy Quote Link to comment Share on other sites More sharing options...
