shadowfax I think you have answered a question from many years ago. My 1960s British cars had natural “live” rubber seals in their brake systems. Girling brake fluid was required as DOT 3 would turn the seals to mush. I’m now understanding that Girling brake fluid/oil must have been a castor oil/alcohol mixture. Thank you.
My 99 Camry Brake light came on when the rear window brake light burnt out.
there was leak at front wheel driver side at Caliper, faulty valve or similar. got that fixed.
I also offer thanks for getting back to us. More often than not we hear nothing, and it feels good to hear of a happy ending.
Happy motoring,
