Boiled my brakes again....
Discussion
Boiled my brakes at Cadwell today after just 2 sessions 
My fluid was new ( dot 5.1, or something like that ), & i have new drilled, albeit standard, discs. My pads are not even 50% worn, but are standard.
My plan, is to upgrade the fluid & pads, but leave discs as they are, as that's really as far as i can go financially!
Does this sound ok, & any tips on the pads. Have been recommended EBC Red pads, will they be ok with the standard discs??
Cheers in adavance

5.1 is not the best, go by the boiling point. The good stuff is usually DOT 4.My fluid was new ( dot 5.1, or something like that ), & i have new drilled, albeit standard, discs. My pads are not even 50% worn, but are standard.

Mine has a 325C boiling point.
Its all about surface area and cooling, two hard sessions at Cadwell is a lot for the standard set-up and not running racing fluid.The other issue with Cerb calipres is that they are one piece billetted so when they heat up they tend to apply a bit of brake themselves!
There are a number of race/track day type pads that don't wear as quick as they are harder, don't kid yourself that they are going to help with heat dissipation and they can be undrivable on the road. Brake pads energy displacement is also a combination of shredding the disc and the pad, so from this perspective they could be worse but they wont soften.
Fluid will only delay the issue by a small amount, you really need to sort out some venting or upgrade to one of the bigger discs with bigger pads and more calipres. However over venting without the right discs can cause cracking from heat-cool-heat-cool etc..
Get it in to Andy at APM or your local race specialist rather than experimenting on your own, cheaper in the long run.

I run Motul RBF600 fluid, standard brakes but with EBC red stuff front pads - seems to work well, the pads work better with a bit of heat in them though. Never tracked the Cerb so cant comment on how this set up would work if it was given a work out like yours!My fluid was new ( dot 5.1, or something like that ), & i have new drilled, albeit standard, discs.

RBF 600 tech - http://www.motul-oil.co.uk/pdfs/brake-fluid/RBF_60...
Seems to get good reviews...bought mine from opie.
Good luck getting a set up...
Try speaking to Circuit Supplies 01525 385888 - Very helpful when i spoke to them and visited them about all aspects of brakes. Really impressed. They are main UK distributor for AP racing and Ferodo.
I went for Ferodo DS2500 pads for 'spirited' road driving as i experienced brake fade with green stuff pads - The DS2500 are used as track day pads too i believe and I saw a lot of people recommending them.

Dont EBC produce yellow stuff pads now...these are supposed to be suitable for track use and work at lower temps...had them on my chim and had no problems?I went for Ferodo DS2500 pads for 'spirited' road driving as i experienced brake fade with green stuff pads - The DS2500 are used as track day pads too i believe and I saw a lot of people recommending them.

I suffer from this also. I'm running the Ferrodos.
A lot of it is down to poor cooling I think. I can get about 5 laps of Spa before they die (pedal to the floor). I've tried Dot 5, Dot 4, no real difference although a slight improvement with the 4.
Next job is to fit some large vents in place of the indicators and duct to the discs combined with some grooved discs to dissipate the gas better.
Other thing to try is altering braking style, later and harder is supposed to be better for cooling not sure how much later and harder I can brake into La Source though!

A friend who races was having issues with his setup and extra venting installed caused him problems rather than solving them. It caused the pads and discs to lose the heat in them after each corner, dropping them out of the temp range they were supposed to operate in. This resulted in much shorter disc life. Keeping everything hot and adjusting the pads to suit the temp range worked better for him. I also remember a vented setup which had significantly accelerated corrosion on a tiv, can't remember it if was a Cerb.A lot of it is down to poor cooling I think.

if you use the right pads with the right fluid you will have no problems. I do not ever run out of braking..ever.
That's good to hear.Which discs have you got?
