Preferred pumping procedure

I've been having difficulty bleeding my bleeding brakes, just can't get the pedal to go hard.

How do people do it?

I tried a Sealey vacuum pump but that just sucked air past the thread on the bleed nipple so I enlisted the help of me girlfriend.

So, three pumps, hold, release the nipple and repeat. Any other methods greatly appreciated because I just can't get it to go hard! Not even *with* the girlfriend's help... Got through a litre of fluid already.

Silicone tube and a pot
Valve in brake lines do play up as do master cylinders
Tap master cyl,push pedal,release,tap master cylinder and repeat

Try Viagra.........

sorry couldnt resist that one.

Keep trying the way you have been, can take a while depending on what you have been doing with the brakes. make sure the person pumping the pedal does it a few times and make sure they hold the pedal DOWN before opening the bleed screw, open screw for a few seconds the close it and get the person to slowly realeas the pedal and do it all again.

ok, try getting the "helper" to press brake peddle hard, then release brake nipple with bleeding tube on so it squirts into a jar,
get the helper to hold down, then tighten bleed nipple- then let helper release peddle
repeat 10 times,
then go to next bleed nipple, but check brake fluid reservour each 10 pumps.


of course, if your brake master cylinder if fooked, then your fooked as your wasting your time until you have replaced the seals/cylinder first,
then it bleeding start all over again

Where do you get this 'pump 3 times' from?

If you have someone ready on the pedal, open the nipple, push the pedal down, close the nipple and repeat until the air stops coming out.

The do the same at the other wheels.

If you repeatedly pump, all you are doing id spreading the compressed air through the fluid.

Try it and you'll probably find that it works .. if it doesn't you have a problem somewhere else in the system.

I just used one of these:

Gunson Easy bleed brake bleeding system | eBay

Worked great, one man job with no help required.

I've had an Easybleed for years used loads of Times on Cars and bikes it's excellent.one man job works everytime.

you wrote wot I was gonna! (cept' I added a bit)

however, I use a spare resovoir cap with an airline fitting in it, a regulator, a clear plastic tube and an old coffee jar. oh, and the compressor.

15-30 psi,and just stand there and smoke, while watching the bubbles creep thru the pipe and bubble up thru the jar.

Thanks for that OSD and nrg. Don't know why we was pumping, seemed like a good idea. Yet another fresh bottle of fluid tomorrow and wheel try again.

Clear tube from nipple into jam jar, end below surface of some brake fluid. Loosen nipple, slowly push down pedal and hold, tighten nipple, release pedal. Repeat until fluid runs clear and without air bubbles.
NSR then OSR then NSF then OSF (for a RHD anyway).

you chucking all the new fluid away you've just pumped through?

i'd be reusing it if it's clean.

Gravity

Open the bleed nipples and leave it until it runs out. Works EVERY time.

Its better not to press the brakes/move the master cylinder passed where its used to operating. Ive seen many master cylinders ####ed by pressing to the floor.

As above, except I've always done OSF then NSF then OSR,NSR.

Are you sure you have all the bleed nipples? There was an extra one hidden above rear axle on my Disco Could not get a decent pedal till we found it.

Normally it's the furthest one from the master cylinder but at times I guess what ever works

Don't forget there is a great deal of air that can hide in a Land Rover braking system. I find I need a few good bleeds to get it all out, with a period of time in between to let it settle. Overnight seems to work well. Especially, the nearside rear carries on producing bubbles for what seems like ages. Persist - it'll all come out eventually. I have one of those pump up things that pressurises the master cylinder which I find very helpful. It would be soul destroying to have to do it with the pedal.

Dunno spent a day trying so ended up taking to the MOT man who done it as part of the test. FREE always good to have a good tester.
