OK, I have looked up the caliper 'sticky', however there appears to be a lot more room to get the dust boot seated than on the twin piston unit - anyone got some tips pls??? Should the seal lip be lubricated or left dry - I have only managed to get about 25% of the circ fitted - the easy bit, but struggling with any further.
If its anything like when I rebuilt the TB48 twin potters those rubber boots were a pain to get on. From memory, I lubed up the boots with rubber grease, tucked them into the slot in the housing and pushed the piston in through the boot and into the housing. I do remember having to use a small flat blade screw driver to tuck in the boot in some spots. I did take a few shots before I got them in.
Thanks for that, I will try and if unsuccessful its down to a brake joint friday as I want this sorted before saturday/sunday for the big change-over.Quote:

OK, done, took about 30 minutes using the method in the youtube clip, so more or less ready to go for Saturday.
Yeah it took me quite a few different shots at it before I got the boots in. I quickly realised there was going to be a certain way to get these boots in, I just had to find it. Tooka bit but I got there.
I tried your suggestion and the boot was dead easy to seat in the caliper, however I could not stretch the inner opening to get the piston in, maybe tried for 15 minutes then reverted to the youtube method.
Yeah I can't remember the exact way I did it but I do remember putting the boot in first, then the piston. Thinking back, maybe I had the boot around the base of the piston, then tucked the boot in position and then slid the piston in. Not sure, but what ever i did worked. Haha!Quote:

Am I better off trying to push the fluid back thru the bleed needle and overflow the reservoir?
‘Gregory’s’ isn’t any “Twin Pot” specific help for your sorry Phil mate!

As mentioned, working alone I used to use an empty 2L ice cream tub catcher below the reservoirs (clutch or brake) and ‘Tom Thumb’ pump fluids back up the system to overflow instead of downward bleeding, seemed to work pretty well back in the days.
EDIT: Consult a brake expert before attempting that :-)

Thanks mark, maybe some jewels of wisdom will arrive from other's here. @Winnie, any thoughts or am I being stupid again!
Nah they are a bastard! Try to push the fluid up through it and if that doesn't work try the gravity method.
