For some inexplicable reason the Stylus started first time today , after a blow heater warm up onto the water temp sensor (did that on Monday with no result ) . All I can think is that leaving on the trailer overnight on Sunday , after driving home from Eelmoor , it condensated in the head with the engine being pretty hot then no amount of whizzing around on the starter was going to fire it up. So that's cleared that mystery.alfablack wrote:Could be Rob, I had a motorbike with six piston calipers notorious for sticking pistons and boy that used to shake its head a bit when you grabbed a handful of brake. that's when you new a service was due. or new seal kits and that was a pain to do properly.
I have some fluid that we soaked the seals in for a few hours then put them in the calipers with rubber grease push the pistons in leaving of any outer seals then put them in a nice warm oven to bake the seals in place for can't remember now think it was 6 hours,
worked a treat till winter had done its thing
I found exactly the same caliper piston problems ie. sticky on just one , in the passenger side today so sorted that out . It was mentioned to me on another forum that possibly there may be something between the disc and hub bolted up face which would certainly cause a wobble. The discs have been bolted onto the hubs since 2007/8 and not been off since , so as the wobble wasn't present till this June at Goodwood , it couldn't be that BUT ----- I did put a little blue sealant on the wheel bolting face to hold some very thin spacers I tried on the front then discarded them as no benefit after driving it. I cleaned off (so I thought ) all the gunge before bolting the wheels back on without spacers. Anyway , today I had a really good look at the surfaces of the ally hub and wheel bolting faces . They looked clear apart from some dark areas showing black against the red hub face . I could barely feel any rise when sliding my finger across it but there was definitely a thou or so above the ally. Tried brake cleaner to no avail then used a very fine blade from a wall paper stripper at a shallow angle and that removed the black slightly rubbery stuff back to the ally hub surface.
I find it hard to believe this may be the cause either on it's own or connected to the pistons sticking BUT ---- we'll just have to wait and see next time on track
