Brake fluid - capacity...

[White Lightning]

Well, I have just received my Amsoil ATE Super Blue Racing Fluid. I've got 1 litre. Just wanted to double check that this will be enough to change my brake fluid... ?

Think you may need more than that mate- poss 1.5 L ?

I think you may be ok ! But you will have to make sure you don't waste any.. I have done it with a litre before ! You do have an advantage though, in that you are using Blue Fluid.. You will then know when the good stuff is coming through.. Use 1 of those 1 man brake bleed kits(Halfords for around £5 though you may need an extra piece of clear pipe to make it easier to see if there any bubbles left in the system. And remember ! Back Left, Back Right, Front Left, Front Right :scholar: And most importantly don't let your resorvoir run dry :thinking:

PS.. I'm doing mine later, so i'll let you know how i get on :D

Cool. Think I will give it a go then. :happy:

Although, being the impatient git that I am I've already ordered another litre /pan - at least that'll be spare for next time.

I went to Halfords at lunch and bought the Gunson Eezibleed. This is the first brake fluid change I've ever done so wish me luck :uhoh:

[Spirit]

Good luck !

Just take your time with the Bleed Nuts.. A wire Brush and a Good fitting spanner is a must :2thumbsup

What size spanner is required?

Would spraying the bleed nuts with WD40 the night before help at all?

[stuartturbo]

I did mine the other week
A good ring spanner 10mm i think
Did not pre lube my where all ok but i would be worth doing the wd40 as the last thing you want to do is snap a nipple/haz

I only used 1/2 Lt but did full drain res first and bleed till new fluid came out so seemed ok /Hmmm

[Kieran]

I recently did this - with a partially drained system, I needed about 2/3 a litre. The bleed nut on my calipers was a 7mm one, -But- I have had my calipers completely refurbished, so the originals may be bigger.

[stuartturbo]

that does make me feel better was unsure if i had bleed enougth

[psbarham]

the bleed nipples (hee hee i said nipples) on both the V6 and VR4 calipers on mine were 8MM

I think you will find that the quantity of brake fluid required is very much dependant upon how worn or new your brake pads are. If they are all new then the quantity of fluid at the back of the caliper piston will be at the minimum and visa versa. Good luck. /juggle

Good Point Don :2thumbsup

Normally when i do full bleed, it is when i am putting new pads in.. :happy:

Thats the best way as otherwise you will be refilling up the resovoir with old fluid that was in the calipers! They people say that the pedal doesn't feel as good as it should and the brakes can fade because of the old fluid. :vogel:

I'm planning on fitting stainless hoses and bleeding the brakes on the VR4 on the weekend.
I've never bled brakes on a car before, but I can do it on an MTB with my eyes closed. Its basically the same but I have one question :)

Should you bleed the brakes with the ignition on or off? Basically should the brakes be power assisted when bleeding?
Also how far should you press the pedal, someone told me if you press it too far you can turn some seals inside out or something.

[White Lightning]

Well, I did mine with the ignition off (I think!) and pushed almost as hard as I could on the pedal when bleeding ... lets see if anyone else thinks differently ...

[bernmc]

You're only going to get power assist with the engine running - works off vacuum. No need for that just bleed with steady pedal pushes and don't let the resevoir run below the min mark. I pushed the pedal to the floor and nothing seems to have turned inside out (erk!)

[Nick Mann]

As said - no need for power assistance. Some people say that you shouldn't push the pedal to the floor as you will push the piston further past the seal than it normally goes. Personally, I don't worry about that and I haven't had a problem. Yet!!+

[Throbbe]

If you're worried, just stick your other foot under the brake pedal to stop it going to the floor.

[mattpage]

Bleed went well. Only small problem was one of the valves didnt want to unscrew.

blow torch on the nut for about 30 seconds will losen them Mat , Sheep lover wrote a good article about this in the members section

[mattpage]

Yeh tried a blow torch, will try it again though. I followed the article, great writeup! :)
