Castrol SRF brake fluid in road going Elan

[holywood3645]

I'm about to fill my brake & clutch system for the first time (all new components & lines, etc) and when I read through some posts I see Castrol SRF being highly regarded by the boy racers (old fart racers... now;-) voom voom!

While Castrol SRF is pretty expensive, im looking on it as, good insurance. I noticed when the car was on the road a few year back, that while I sat in traffic in the hot california sun; the clutch would become very difficult to engage. I thought this was because of the close proximity of the clutch slave cylinder to the exhaust maniford. It only happened in slow traffic on very hot days. The problem disappeared when I got moving and air circulating around the important little parts.
Castrol SRF has a much higher boiling point than typical brake fluids and think this may be a good application.

Thoughts, ideas, your 2 cents worth?

Thanks

SRF or other competition brake fluid is probably overkill for the application. Regularly changng with fresh good quality fluid should be sufficient for any road car.

Changng your fluid one a year is better than buying an expensive competition fluid and not changing it on the same time basis

Thanks for the reply. But what about my clutch problem in traffic on hot days?
Do you think the higher boiling temp.would help. SRF is 70USD /ltr over here

Why not put a heat shield over the slave cylinder? Cheap and easy.

I suspect your clutch problem was water absorption into the fluid. Change the fluid for fresh standard fluid and it should be ok.

The steel clutch line to exhaust header clearance on my elan was around 2mm but i never have any problem with the clutch. I use standard DOT 3 fluid in the clutch. i am just in the process of fitting a TTR header and this increases the clearance to around 5mm
