After a good day of timing and tuning the carbs I was ready to rock but less than probably two miles later the NS (drivers side to me as LHD) wheel was hot and smoking. Clearly the caliper has frozen. I also heard some clicking which I guess may be a cooked bearing? Anyway, I think I have a refubd item to go on but if not, Bigg Red is only 3 miles away so I'll get them to refurb. Question is, is the caliper likely knackered if it gets that hot or is it likely to go again? Apart from new discs and pads am I looking at regreasing the bearing or replacing?
Ok I think for what they cost probably worth replacing anyway. Ive just found a reconditioned caliper that's been in the garage for 10 years - is it correct for the side I need? It's marked "L" but not sure if that's taken from inside the bus or facing from outside:
Might be able to get a caliper rebuild kit and strip them down,refurb. I did mine Sent from my iPhone using Tapatalk
If it’s got two possible positions for the bleed nipples, so one can go at the top, should be ok - assuming it fits.
Also, before you put it all back together with the new caliper etc, consider the condition of the flexi hoses. When I recommissioned my van after a lengthy lay up I had a lot of issues with sticking calipers. Fitted recon items (which were tricky to bleed - and a clue!) but low and behold, still had major problems with binding and uneven braking. The problem all along turned out to be collapsed flexi hoses which were allowing fluid to pass one way under pressure but not return and hence release the pistons... Verses an in tact section...
I last changed flex hoses over 10 years ago so I may as well do them now seeing as so much needs to come off.
Still not certain what has failed but 80% sure it's the caliper. On removal no brake fluid is present but the line itself is dripping brake fluid nicely. That said, there is a small kink in the hard line so I will make up a new one of those anyway: The hoses seem to be OK tbf. I may replace them anyway. I've checked run out on the disk for warping but it only moved a mil on the DTI so think it's ok. Plenty of meat left though it does have 'positions' on it from the pads when sat: What do you think? Pads arent looking too clever so will def do new pads both sides: Other than that the caliper will be refurbished and the replacement used for now: I can see no real difference in these two apart from some areas in the casting.
Nope the caliper doesn't fit. Looks to have an offset to it of some sort so must be for the other side. Edit: the bolts don't fit either so that reconditioned caliper must be for an earlier bay. You'll see it shortly for sale then!
Those discs look quite badly scored to be honest. I'm amazed you got those calipers off without taking out the pads, and they are proper manky. I think you were lucky Rebuild kits are about 20 quid for pistons and seals, why would you not! Plenty of heat on the bleed nipples to remove and they'll be recoverable. No fluid inside because you'd boiled it away. Change the rest in the system while you're at it
Fair enough. Bearings sound like a train running down the track too. So discs, pads, bearings and a caliper it is. But I'll recondition both calipers anyway now. Where do you get rebuild kits for 20 quid?
He's very helpful ar Bigg Red He supplied me a mixed set as we have Girling caliper one side and Ate on the other and the seal on them is slightly different.. Sent from my SM-G960F using Tapatalk
I called them this morning and they can turn both around in 3 days. As much as I'd like to do them myself I don't have the time so for the sake of 2 hours labour charge I'll drop them over to them instead. Now all I need to do is work out how to change front wheel bearings! Cheers all
Easy enough, just follow your nose. Din’t forget the outer races need changing as well as the inners.
Do they need pressing in and out? The OS side feel and sounds ok. I also dropped my calipers to Bigg Red. Again, the OS seemed to be operating properly but getting them both done as a matter of course now its all apart. Should be back by Thursday.
