As above, mini sport 4 pot alloy calipers for vented discs. Been spending most sunday mornings bleeding these, keep getting air locks. I snapped one of the horrible little m7 bleed nipples that go into the adaptor that goes into the caliper. So i chucked that in the bin and went straight into the caliper with an m10 bleed nipple. The system seemed to bleed better.... Now ive just checked the calipers, a week later and there is brake fluid seeping out. Only a little, but still, it shouldnt be!

Anyone got any tips on how to resolve this? It seems to be leaking around the threads.

I hate these crap calipers, please dont anyone buy them!!!!! They are so badly made and designed. Buy KAD instead!

Send them back to minisport. the threads shouldn't see andy brake fluid as the taper part locks it off. and the hole through the middle diverts it to bleed the system.
I do think you may be being a little heavy handed if you have snapped a bleed screw. They don't need to be that tight

Iv not had any problems with my callipers. The M7 bleed nipple is the same as a metro turbo callipers bleed nipple.
The insert you talk of is so that you are not securing a steel bleed nipple into alloy as this often siezes. by fitting an M10 nipple into the alloy it may well sieze then snap next time you need to undo the nipple for bleeding.

bleeding wise, your bleed nipple is fitted to the top?... i.e you havent got the passenger calliper on the drivers size and visa versa.
If you still have problems try fitting a block of wood between the pads and while an assistant is depressing the pedal, rotate the calliper, if there is any trapped air bubbles (unlikely to become trapped due to design) they will hopefully find their way to the bleed nipples.

I have these calipers, was a little bit of a trail to get the nipple to completely seal but they do eventually if your patient, mine did weep but that was due to the nipple not tight enough (fear of snapping the blighter) once i did them tighter no problems and stop the car on a sixpence

As Mini93 says they only go on one way round with the bleed nipple uppermost

[minidaves]

first point of call minisport!

No problems at with these on mine and they have been on well over year now.

Might be worth as others have suggested, give Minisport a call, especially before you slate their products over a problem that might be unique to you.

Best of luck
