Default Brake bleeding

How long should it take to bleed brake lines from dry? I have just been trying but with no success. I have also tried my eazibleed kit and that's not working either?

Has anyone got any ideas what I'm doing wrong or is my master cylinder knackered? (Mx5)

Took me about half an hour
I used a syringe to inject fluid in through the caliper bleed nipples.

Thanks.

I will try again tomorrow. I got the occasional bubble in the jar but didn't seem to be getting any fluid coming out.

I will try putting some in with a syringe as well

David ...I bled mine from dry and simply started from the nearest to the MC and then the next nearest and so on then re-bled the whole lot in reverse order try it and see.

David,

If theres nothing but air coming out the calipers, whats the fluid level doing in the reservoir?

If its dropping, the fluid must be going somewhere. Check all around the lines/joints/calipers for leaks. If theres no leaks, keep at it.

If the level doesn't change, you've probly got a blockage somewhere.

thanks


i will try again tonight and keep going a bit longer!!

when I did the clutch I used the eezibleed which worked a trick. it doesn't work well with the brakes as i had to buy a really large universal cap that doesn't seal very well.

If the master cylinder is lower than the calipers you may have a problem at first getting the fluid to the calipers.

Possibly open the bleed screws with the calipers hanging down and let them drip and see what happens .

Have a look and make sure piston is not stuck in.

If at first you dont succeed,avoid skydiving...

If your mx5 has abs, it may need to go on the computer to be bled via the abs pump. My golf was an absolute cow & had to go on the vag system. If it hasn't got abs, I would start checking for loose fittings. Maybe the system is sucking a little bit of air from somewhere, and air compresses easier than fluid. If this is still playing up after a quick check, I would strip the master cylinder and fit new springs & seals to it. Master cylinder rebuild kits are available on the net for about £25. Oh, have you tried bleeding the clutch ? Think it all works off the same system on the mx5. But you may need to confirm this.
