Brake Bleeding Kit

Doing this with older vehicles will find any weak points in your system!

Newer vehices have high pressure brake systems, so need them (manual will never get a good pedal) - older ones, such as the landy, have low pressure systems that you can do manually.

When using high pressure bleed systems on these - many complain that they end up replacing servos/master cylinders etc. This is normal as any weak points will be blown out with the high pressure bleed.

That's interesting. I have to admit I prefer the thought of pulling the fluid through from the bleed nipple end rather than pressurising from the reservoir end but I hadn't thought of the possible damage it could do to the master cylinder by applying pressure to it (no servo on mine).

I assumed that the amount of pressure exerted by the pressurised brake bleeding kits would be less than what would ordinarily be applied by pushing the brake pedal down, after all its not going to need 120psi just to push some fluid down a pipe! But thinking about the pressure in my tyres it might be best to avoid the eezi bleed kit that uses the spare tyre pressure to push the fluid through as that might be a bit excessive?

Thanks for your reply - it has provided more food for thought!

I guess the syringe approach would be the safest bet for solo bleeding ?

I don't see the problem there...if I used one of those bleeders and it found a week point, I would be happy, and then replace it! Parts are not expensive for these afterall....would rather replace something that is on the way out rather than wait for it to fully fail.

Hi,

It doesn't matter what you do, air will always be trapped above bleed nipple height in at least one cylinder.

I tried to work out ------ if you ran a flexible hose to each cylinder, and fitted bleed nipple in each cylinder too ........ but my brain started to hurt.

This may sound silly (coming from a break bleeding virgin) but...

If you replaced the last few inches of break pipe with breaded flexible hose. Then you could clamp the cylinder with a G clamp or something similar. Then you could rotate the cylinder so the bleed nipple is on top and get all the air out???

Then fix it to the back plate add shoes and drum..... Job done... Maybe ??

I'm no bleeding gigolo myself!!! (took me ages to think of that), and i certainly know nothing about braided flexible hoses - I'm not sure it would be an easy job to source the right length with the right connections?
