Brake fluid question - ZR-1 Net Registry Forums

secondchance · 10-20-2009

I will be flushing brake fluid for a 94.
Does anyone know how much fluid I will need?
Also, any specific brand you would recommend?

Any special procedure required for flushing out the system w/ anti-lock system?

Thanks.

ATE super blue from tirerack will let you know when it's totally flushed, I use ate type 200, is same stuff, just not blue. Less than one quart got it done on mine with all the brake calipers compressed, took a long time with the pistons extended. I've done mine about 6 times this summer so I didn't worry about the anti-skid. Castrol SRF if you really want the good stuff but it's $75 a quart!

Ant-lock no, but there may be something I don't know re: traction control.
I flushed a friends 92 at a track a long time ago and ended up with a worse pedal so I did something wrong. Mine's a 91 and I just do RR, LR, RF, LF and it's good to go. 92-95s have traction control - right?

And ATE Blue and Amber are the best bang for the buck.

Yes. It has traction control.

Then use the bleeding procedure in the 92-95 FSM, it's probably different than the 91 and earlier cars because of the traction control.

Thanks.
I will be rolling up my sleeves around 3.

For the FWIW department, our 91 has suffered from soft pedal since we bought it. Two different shops flushed the system in the traditional order as you used (while also doing stainless lines and a new M/C), but no joy. The ABS has no fitting. Finally I RTFM'ed and found the FSM order is RF, RR, LR, LF. Sensible if you consider the distance as being from the ABS unit. Got a giant burp out of RR when we used this order.

Also FWIW (I only autocross, no track), can't beat the Ford heavy duty brake fluid. Cheap and about the best wet boiling point, which is what matters if you don't flush more than once a season. Of course, I'm an old Ford guy so YMMV...

Two pints covers it. I think with all the bleeds we tried I've actually run about 8 through it. Cheap matters at that point!

Cheers,

After installing new rotors I vacuumed old fluid out the top reservoir. Then vacuumed old fluid out at all 4 calipers while filling the reservoir from the top. Sequence was RR, LR, RF and finally LF.

Pedal pressure is good and high speed pulsation with the brake applied gone.

Mission accomplished!

Ford HD fluid is cheap and pretty good, but its dry boiling point deteriorates quickly once you boil it. I used to use it, but converted to ATE when I saw all the BMW guys using it.

And I'll try the FSM bleeding rotation the next time ...
