Brake fluid

[Powderpuff]

Ok, simple question...I hope.

 

Which is the most suitable brake fluid to use in a standard braked k series for road / trackday use.

 

See, told you it was simple (but not to us accountants)

 

Ta.

Bit of a downer on accountants at the moment, but here's my 2p anyway.

 

I use Halfords DOT 5.1. The pedal is rock hard all day on the track and on the road there's plenty of feel. IMHO go for anything else and feel the pedal hit the floor after a few laps. sad.gif

 

Of course, real racing drivers don't use their brakes, so I'm just saying what other people have told me. wink.gif

 

Cheers, Davebo.

 

See I don't hold a grudge.

p.s. Sorry you have a downer on accountants at the moment, but it could be worse, I could have been a lawyer teeth.gif

No,

I need one of those to defend myself against my acountant. mad.gif

 

But, hey, that's life. He doesn't have a 7 and I do. teeth.gif

Fresh stuff.

 

I'm not convinced that what you actually use makes much difference, but DOT 5.1 isn't expensive enough not to use. Change it every spring.

 

If you want 'ultimate' because you can then AP600 works well. But it only lasts 3 to 6 months. If you don't keep it fresh then you might as well use DOT3.

I also use DOT 5.1 to my satisfaction. Use Easybleed to change it, its piece of cake. I know, Anna will be disappointed not to serve anymore as the bleeder assistant ...wink.gif

Can you flush a DOT 4 filled system through with DOT 5.1 or do you have to empty it all out first?

As far as I was advised prior to undertaking the very same task a few months ago, the non silicone fluids are all okay to 'mix'. By the the time that you've bled the system thoroughly enough new fluid will be in the system to disperse any of the old stuff. Not too bad a job in all and good for peace of mind.
