Bloody bloody bleeding brakes !!!

[Peter-C]

A couple of questions on brake bleeding.

How long is a long session ? Is it 10 Minutes, 20, 30 ?

Do you have to every tiniest bubble in the world out.

I'm asking because I'm getting absolutely nowhere. The brakes hardly work at all and the the pedals as spongy as buggery.

Am I doing it right, start at the rear nearside, undo the nipple 1/4 turn , press down pedal and then tighten up and release pedal moving on to rear offside, front near, front off. I've removed the brake pressure sensor and pumped brakes. Stll no change.

Any ideas please ?

Cheers

Peter

Tiniest amount of air will gve you a soggy pedal,air is compressable fluid is not.

If you have rear calipers make sure they are bled with the nipples upmost even if you have to remove and place them on the disc elswhere to bleed,if you have rubber flexy hoses clamp them gently and try pedal,let them off one at a time and you may find the air.

Cheers,

The rears are drums with new cylinders and the hoses are the braided flexible ones.

Another stupid question, I assume that you carry on with the first one till it is absolutely clear and then move on, rather than get it almost clear, do the rest and then start over again.

I remember AshG having problems ages ago, I think I'll beat that !!

I'm totally hopeless at brakes, I even sold a car because I was that frustrated with them.

I'm nowhere near doing my brakes yet but this is my procedure for replacing fluid. I use a Gunsons easi blead and it never fails. First off I drain the old fluid using the easi bleed to force the fluid out starting with the wheel furthest from the master cylinder the doing the others finishing with the closest to the mc.

To refill, connect a hose to the nipple of the furthest wheel cylinder and put the other end into a jar or jug. Fill the easi bleed with clean fluid and pressurise. The fluid will rapidly be transferred into the system, as required top up the easi bleed. When fluid runs clear from the hose without too many bubbles close the nipple and move to the next nearest wheel and repeat.

Once you have done all wheels go back to the first one and go again. If the pedal isn't good then I usually leave it half an hour with te pressure off and then bleed the traditional way with an assistant pressing the pedal. Its never failed me yet.
