How much Brake Fluid?

[Throbbinhood]

Just wondering if anyone knows how much brake fluid I need to do a full flush and get some air out of these lines!

Single piston calibers, GQ LWB, doing all four plus the bias valve at the back which I believe I start at.

About half a bottle but you will use more bleeding it.

So you think 1L would be enough including bleeding?

All new pads and rotors if it helps.

[Winnie]

Should be, but I would buy 2 and throw the second one in the back of the car incase you need it.

X 2. Cheap as, and you may as well do the clutch while you have the gear there already. Just remember to whack a block of wood behind the pedal, so you don't push the piston past its normal range when you are bleeding the system.

Thanks guys. Anyone gravity bled a system before? Will most likely be doing it solo.

Can I gravity bleed the clutch? And do you know where the nipple is for it? Does it also take DOT3?

Gravity bleeding is a pain to do and is slow. Best way is to get some clear pvc that fits snug over the bleed nipple. Get around a metre long. Get an old bottle, only need to be 500ml or so. I used an old 500ml brake fluid bottle. Make a hole in the lid and push the hose in so it sit on the bottom of the bottle. Put a small amount of fluid in the bottle enough to cover the end of the hose. This is so you don't suck air back up and into the cylinder you want to bleed. Then put the other end of the hose onto the cylinder you want to bleed, open the nipple and pump away, watching that you dont run the reservoir dry.
If you doing all four wheels, start from the furthest cylinder, rear lhs and work your way forward, not forgetting to do the bias valve aswell.

Ok no worries. Mudski would you do the bias valve first, or third as per longest to shortest?

And any idea re the clutch bleed and where the nipple is/same method/dot3?

I think I did the two rears and then the bias. It was a while ago. You should have a bleed nipple on the clutch slave cylinder. Some GQ's have the bleed nipple on the line somewhere too from memory. Same fluid too.

I saw our mechanic at work uses one of these bleeder tool kits...

So I ordered one off eBay $17 !
I still wouldn't have a clue nor have balls to touch my brakes, but it's a nice tool kit to have around.
