car is a 1989 1.6 classic


changed front discs an calipers to 4x4 twin cam calipers

put all on

tried to bleed

pumped a few times then pedal hit the floor but now wont stiffin up again?
put old caliper back on and the same

took off an pumped an its not even dripping?

plenty of fluid to an was grand before changing

any ideas

 

Sounds like you may have damaged the M/C, did you push the pistons back on the new calipers?

Not that it will make any difference but assuming it's a conventional servo have you tried starting the engine to "Re charge the servo" so to speak?

yea tried startin the engine
no difference

anyone got a correct guide on how to bleed them?

im going to try get a M/C now an retry them

is there any order you do them?
car started or off?
brake fluid cap on or off?

 

If it's a NON ABS model, you can bleed in the conventional "Two man" method, start with the wheel furthest away from the M/C, so in the case of these cars thats the nearside rear, working your way toward the M/C.

i.e. offside rear, nearside front, offside front, leave the cap on, engine dosen't need to be running either.

ah ok
i got a M/C there

so start pass rear, pass front, rear driver an then driver front?

 

No furthest away to the closet, so, NSR, OSR, NSF, OSF.

ah got a mechanic to take the car an install the M/C and bleed the brakes
