Hi there,

Anyone know how much brake fluid I need for my 2.2 Brera?

Also, what would you recommend for an upgraded fluid - something that can handle more heat? I've got DS2500 front brake pads and they are great but develop a lot of heat on track days.

Finally, do I absolutely have to have braided hoses? I haven't upgraded those yet as the brake feel is good and stopping power is good.

Fluid - we use ATE Superblue. Its a good fluid, high temperature rating, not too expensive, and the blue colouring makes it very easy to bleed (you can also get it in 'Gold' for when you change it again in ~2 years time).

Hoses - you don't have to have braided. As your hoses get older they will get worse, so they may be OK now and stainless braided hoses won't make much difference, but as your car gets older your rubber ones will expand more and more.

Ah that makes sense, thanks Dan.

Any idea approx how much brake fluid I need for a 2.2? I saw another thread on here where mehstg was told he needed 0.5 Litres for his 2.2, but in the same thread SR suggested he needed close to 1.5 litres from the Brembos on the 3.2... surely there can't be such a massive difference?

 

[Pud237]

Most cars use roughly 2 litres to fill the reservoir, all 4 calipers, the ABS module and the brake and clutch lines.

Ah right, cheers. Is that the ATE Super Blue Dot 4? It's not too expensive at all - about £20 a litre.

 

[Pud237]

Yeah Dot 4. Most racing fluids are Dot 4, they vastly exceed all the specifications of a Dot 5.1 fluid (what the car is specificed with) except for longevity, so they mostly get specd as Dot 4.

 

[Commanderfish]

Right that makes sense, thanks Dan. I had assumed that DOT 5.1 was "better" than DOT 4 as far as operating tolerances go so I am pleased to stand corrected!!

Bloody hell, ATE Super Blue has a higher wet boiling point than Castrol Response Super Dot 4, which costs £45+ a litre!!

 

[Pud237]

I did say it was good s*** mate :lol:

Very good, had it my GTA, make sure you buy new stuff though, apparently some is being sold off cheap as it is old stock, one of the sites selling it has the info.

Castrol Response Super DOT4 is only £13/L (renamed to "Castrol React Performance Dot 4" now).

It is Castrol SRF that is around £50/L and that has a far higher boiling point.
