tips for bleeding brakes
lrmike:
I've got a miti vac and works great! Just don't loan it to your mate who doesn't pay attention to the level in the jar and sucks it through the pump ](*,)
Thank goodness for rebuild kits!
I've had good luck with gravity bleeding and then a great wife to pump the pedal a few time to finish the job.

With the dual-circuit you need to bleed the nipple inboard first at the same time as the top one, then blled the outside last, if that makes sense. the two lower nipples are joined by a tapping in the bottom of thw calliper so you can't bleed the outside piston first. The top niple does the top pair of pistons.
if it won't start bleeding try opening up the unuion on the master cylinder and bleeding the system there first, any air in the master can stop successful bleeding.
Also, bleed the back brakes first.

ok
is there any caliper i should do first? or just do back then the fronts
so i do the top one and the one nearest the engine then the one pointing out towards the wheel?
cheers again

You always do the furthest from the master cylinder and work to the closest, so passenger rear, drivers rear, passenger front and drivers front.

Yes.
If you are using EasyBleed it's not as important but for 2 man bleeding you should bleed both circuits together, apparently :?
Always start furthest from the master cylinder, as the unbled air gets compressed so the more of it you have in a pipe the harder it is to get it all out.
IO also like to retract the pistons into the callipers with a pair of pipe-grips (or big pliers) to check the piston isn't seized and help work the air out of the calliper.
