How much brake fluid for a full drain flush and change?

[Victor Meldrew]

Brake fluid boiled at knockhill after 15 laps.. No pad fade at all with Carbon Loraine pads and AP disks..

I was planning to change out the brake fluid, which is probably over a year old now for a higher spec competition version.

The "racers choice" is £50 a litre.. which for a once a year change on car that takes a real hammering I suppose isn't to bad.

However, if the esteemed wisdom reckons that I will need two litres to do a full drain & flush (£100) the the cheaper stuff beckons.

I reckon your better just flushing the normal fluid more often, than the super duper stuff once a year

Never boiled brake fluid in the Elise, thousands of laps of KH, 175bhp engine, late braker . . . used/use Castrol Super DOT4 changed once a year . . . 50 quid a litre is a waste of money

$0.02

i just flushed out my full system tonight, as i boiled the s2 on standards pads+disc coming over applecross on 050709, lost all brakes for around 30 miles, the handbrake became a very good mate!

you would be right on needing around 2 litres to flush the system, what i would suggest is you flush out the fluid on each corner, starting n/s rear, then n/s front, then repaeat for far side, until you are pulling through new fluid, i used dtandard cheap fluid - didnt see the point in wasting good stuff to cleanb the pipes, my next step is to replace with this stuff,

Ate fluid, alot cheaper per litre and still very high quality

to fill the s2 from empty you are looking at 3/4 of a litre - so i was told buy the guys @ MMC

anyway, hope this helps you - oh and dont break a bleed nipple like i did, anyone got a spare for the front (need to drill mine out!)?

Kind of what I thought, why I asked the question first rather than diving in and buying some..

I put ATE super blue in a year ago as well and never had a problem with boiling or brake fade.
