Changing Brake Fluid - ABS

[blueST]

Is there any difference in bleading the fluid through on a car with ABS compared to one without? I have done it numerous times before but never on a car with ABS.

[tegwin]

Nope... no difference...

Some earilier ABS pumps have a bleed nipple on them so you can purge the air out of them.... But if you are simply replacing fluid for fluid.... just bleed as normal... preferably with a presuised bleeding kit

[blueST]

Got an Ezibleed so should be straighforward then. The car's a Laguna, the recently discontinued model.

Do you need to pump the brake pedal when pressure bleeding brakes or just let it get on with it ??

The Ezibleed removes the need for someone to pump the brake pedal.

[chazzer]

Thought so, thanks for clearing that up

ABS has more hidden/blind parts for air to collect.. so it can be very hard to get a decent bleed if you let all the fluid out; best plan is to keep it topped up and cap any hoses you take off.

You can easily use the pump the pedal method.

Keep the fluid topped up.
Don't turn on the ignition.
Check for a bleed nipple on the master cylinder aswell.

I don't know how true this is, but if you lose fluid I was told be the dealers to have teh ignition on whilst bleeding to open teh abs valves allowing the system to be fully bled. Rubbish or truth? I don't know. It worked though, so happy days. Just a thought. I had a hose fail so lost a lot of fluid, if its just flushing new stuff through it may not be necessary at all.

I agree with the ignition on comment when bleeding ABS cars
it definatly helps when gravity bleeding

TBH I'd always get a mate to help rather than use one of these one-man efforts.

It's always worked fine for me, but I've got no mates. Seriously though, not quite as practical as they require a bit of messing about, but perfectly acceptable in my experience.

Properly set up, Eezibleed works much better than the pedal pumping method. People that don't have luck with Eezibleed tend to be using the wrong caps for the master cylinder, or have perished seals in them etc.

I've been bleeding brakes for years & I don't get on with an Eazi Bleed! Bought a draper speed bleeder that uses the compressor to create a vacuum & suck the fluid from the bleed nipple. Had issues in the past bleeding brakes by pumping, A. Because it isn't always possible to get all the air out & B. damaged the master cylinder seals because the piston is travelling in parts of the bore where it doesn't normally go.

Be warned if you let the system run dry and use a vacuum bleeder you will struggle to get a pedal with certain ABS systems,i would syringe the master cylinder then top up with new fluid then bleed as normal if you plan on the pedal bleeding method then you can use short strokes so as not to damage your used master cylinder seals,vac is much easier and less likely to cause any headaches though the motor trade don't generally use the Ezibleed that's more of a DIY product i have heard it works OK though.
