75 1.8 and cdt front Caliper seal again
I've a real and recurring problem with this on 2 cars - anyone had same or got advice? The caliper piston dust boot fits over the lip of the caliper assembly -unlike other designs it does not seat inside the piston. The boot has a reinforced metal ring at the seat. The problem when fitting these is that it does not want to sit all the way round - the metal ring on the seal is evidently just a fraction too small. Seat it on one side and it pops up on the other. On a tally of 4 calipers this is a problem on 2, from 2 different cars. the other 2 are fine. There is no excess corrosion or paint. I have tried boots from 3 different suppliers and all have same issue on those calipers. Help?!

You just have to persevere and use all 4 hands. They do go on eventually

Re: "Dunk it in boiling water and then try."
This works perfectly. Place piston in caliper with the dust boot groove about a centimetre proud of caliper lip. Put the dust boot seal in plastic bag to keep dry, leave in boiling water 5 mins then place around the back (blind) side of caliper rim first pushing down, finally push down over front while still hot. Slip seal into groove in piston all the way round, and push piston fully in to allow fitting of the new pads. After it cooled there is no sign of the seal coming adrift from the lip. So the heat expanded the metal reinforcement ring just enough to allow fitting and now a good seal. Thank you! |
