i use 5.1 and i'm needing some more but can i fook remember....think it silicone based i need but please comfirm...........

 

nope, non silicone is the stuff

 

.....cheers fella....nearly fukd up......lol

 

silicone stuff is DOT 5. and will eat your seals in the brakes...

almost an moment! lol

 

so 5.1 is all "non silicone"....????

 

not entriely sure. cant find the site i used the other day... but it explained that all DOT 5 fluid is silicone baised, and gave the boiling figures as higher than DOT 5.1 but it eats seals. hence DOT 5.1 (Glycol Based) is used as it has a longer brake life and doesnt eat selas...

HTH

 

halfords 5.1 1ltr about Ł12.....seems cheap

 

Silicone fluid is compressible compared to normal fluid and also as it is non-hygroscopic it means water will collect in pockets in your fluid rather than just being 'held' within it.
This can lead to problems in very heavy braking and with brake pipe corrosion

 

Correct.
