Brake fluid
 

I was thinking about trying RT700 or SRF this year.

Motul RBF600 is $40/l
Castrol SRF is $60/l
Torque RT700 is $70/l
Endless is $80/l

Anyone have feedback on Endless, Castrol SRF, or Torque RT700 fluid in a Miata application? They all appear to be better than Motul 'on paper'.

Do you cook the RBF600? It has great pedal feel, so if you're not overheating it, I see no reason to switch.

I just filled my car up with SRF, but that's because I already had a bottle on the shelf. It doesn't have quite the pedal firmness of RBF600, but you also pretty much can't kill it.
