Brake fluid

[Geokor]

Owner of a Williams...I need to bleed the brakes and I was looking for a better braking fluid...I ve seen motul rbf660 ,has anyone anything better to recommend? And also how many liters do I need? Thanks a lot !!

If you use the car just on the road I probably would go ATE Typ200. The Motul is great for track use but might be a little over specced for road.
RBF600 is slightly cheaper if you want to stick to that brand.

We can supply all of the above here and others like Castrol SRF which have a really high wet boiling point so suitable for high brake temperatures and where a car is left for a long time between maintenance fluid changes.

Usually with no air 1 bottle will flush through the clio.

Thanks for the help guys , so do I need only half a litre? Or 1litre ?I use the car for some b road driving and some trackdays...also

What pads are you using?

What pads are you using?

I be just bought some pagid standard bads since I have the car nearly 2 months ,and I want to test some standard pads and then try something better like rc5 ...what do you recommend?

 

[Kev@KAM]

Ok. If you are running pagids then you can run some of the cheaper stuff.
However when you upgrade to CL brakes - because they are a metallic compound theres a bit more heat transfer to the caliper and fluid than a ceramic based pad so you want the best you can.

you are talking about the fluid right ?

 

[Kev@KAM]

Yes. Your average oem pad will overheat before something like ATE typ200. However the CL are designed to run at extremely high temperatures and usually the fluid becomes the weak point which is why you would need something more top end. For more critical race situations we run thermal backing plates on customer race cars if we think theres a risk of the fluid overheating

So you suggest trying something simplier with these pads ?

If you are bleeding them by topping up then 1/2 litre will be enough, if you use something like easybleed where you use an external bottle then 2x 1/2 litre some of which you can re-use.
I use RBF600 for fast road and occasional track with DS2500 pads and all seems good but Kam Racing and George far more knowledgeable than me

 

[Kev@KAM]

If you are planning on running the CL Brakes RC5 in the next 5 months then Motul RBF660 is about the minimum I would run.
Otherwise go for the cheaper ATE Type200 or SL6 and see how you get on.

Ok guys thanks a lot for the info !!

can see specs of a few popular fluids on RTR Parts, if running OE pads, a litre of the Ate typ200 aka the supergold fluid will be ideal. I supply a lot of it https://www.roadtrackraceparts.com/shop-by-parts/braking/brake-fluids.html
