I have installed my brakelines and MC. I filled my resevoir with fliud and tried to start getting it around the system, bleed brakes etc. Nothing seems to happen when i press down the pedal. When i took off my rear callipers some fluid was appearing to reach there when i unscrewed the brake cable. On the front callipers i unscrewed the bleed nosle a tad and nothing seemed to happen. Then i went back to the master cylinder and unscrewed the first line (to the rear) and pressed the brake pedal, no fluid at all. Is there an air bubble in there? If so how can i fix this problem?

Thanks for any help

So you are saying that no fluid comes out or the mcyl holes when you apply the pedal? Is it a new one? Could it still have blanking plugs in place? A blockage in the reservoir?
Sounds a bit odd to me :/

No blanking plugs are in place, and its brand new from MK

Hi C6H6,

If you have correctly connected up mcyl to the brakes, then repeated pedal/mcyl applications will eventually deliver fluid, so long as you keep the mcyl reservoir topped up (to prevent air ingress thru reservoir, into system).

If there is still a problem, you may have a kink in the brake pipe, which prevents fluid flow. Check this out.

Moreover, if you have disc brakes all round, try bleeding the fronts first (longest front pipe run 1st), then bleed the rears (again starting with the longest rear pipeline).

Do you have any sort of valve between mcyl & rears?

What mcyl arrangement - tandem or binocular?

You are locking the bleed nipple before you release the pedal aren't you? Or use a bleed tube with the end submerged in a jar of brake fluid. When you remove a pipe from the m/c can you feel any pressure if you put your finger over the hole and press the pedal?

When it was new and unconnected, the pushrod was not pushed in or when first installed and empty it wasn't pushed in before any fluid was in?

The M/C when new is empty and operating it can cause pistons to bottom and not return due to seals being dry. The return spring on occasions can't push piston back.
Try tapping the M/C gently with a small mallet see if it clicks back.

Thanks, i'll give that a try

not entirely related, but i would strongly recommend getting an eazybleed kit. it uses tyre pressure to push fluid thru from the resevoir. simply walk round undoing one nipple at a time, and wait for the flow to run clear. twice roind to be sure.

also, make sure your brake switch points down, to avoid any potential airlock.

ps, with the easybleed kit you could see if there was a block, cos you can see the fluid leave the container.

Cool, where may one be able to purchase said easybleed?

Just about anywhere that sells bits for cars!

Try Alfuds

yup, i got mine from halfrauds, about £12 or something... blinder. worth it even for one use.

I would answer that but to me it says "XZydud or asdhbucin?"
