Brakes leaking within 200 miles-dot5 fluid

I work in OEM brakes and we do not allow the use of the Silcone brake fluid in anything. It may not be compatible with some of the EPDM parts in you braking system. Usually brake fluid has agents in it to both keep the rubber soft and help them seal. The stuff also has really unstable compressiblity so it's not so repeatable.

Use Dot 3/4/5.1 glycol from a good name brand. ATE SL.6 is probably some of the best stuff but ideally you'd want something with a good boiling point...
