Morris Minor Owners Club

Hi guys
in the process of fitting front discs,servo and a new m/c with a remote reservoir
and new brake pipes is it worth using silicone brake fluid or stick to dot4 ?

If you have new brake components, silicone is an option. I use it and have had no problems, wheel cylinders don’t tend to seize up with this fluid. It’s more expensive, so many people still use dot 4 and are happy, so it’s a personal choice,

New system - silicone.
Had it in the Morris for over 10 years never had a problem. I would have it in our other cars if I was starting from scratch, instead it all has to be replaced every 2 years - a bit of a no brainer in my eyes!

I replaced the whole braking system in the 1990s and have only had to replace silicon fluid when I had to replace the master cylinder two years ago. It is much more expensive, but my rear brakes never seize up like they used to.

Silicone every time, no contest. As others have said, it virtually removes corrosion of components and never needs changing. Moreover, if you spill any then it won't act as paint stripper. I've had it in the travellers with discis and the saloon with standard brakes for over 25 years and no trouble at all. You must observe cautions about flushing and changing seals is swapping from DOT4.

Hi,

Following up on your thread as I have a similar question.
Did you ever manage to fit a brake fluid reservoir tank for use with silicone brake fluid, if so would you be able to help me in sourcing a supplier of a similar kit please?

Regards,
Robert

Never felt it necessary.
