Only noticed it this morning, hasn't done it before. Only comes on when I apply the brakes. What could this be? It doesn't happen all the time when I brake. Doesn't seem to have any effect on the cars behaviour at all.

check your power steering fluid resivior, on the drivers side of the engine bay... its probably a bit low. Use dot 5 fluid i think.

yep, most likely PAS fluid low. The hicas has a low fluid sensor on the top of the resevoir.

 

However, dont use dot 5 fluid!

 

You want Dexron II/III/VI Fluid. Does'nt matter which they are all compatible,. Typically listed as Auto transmission and Power steering fluid.

My bad... i just checked and i used dot 4 brake and clutch fluid.

 

Why shouldn't you use dot 5 out of interest?

I think it contains a solvent, and it doesn't agree with old pipe work, maybe not a solvent, but something, i think :)

Hi mate

 

Brake and clutch fluid is just that - for brake and hydraulic clutch systems. Power steering mechanisms use auto transmission fluid - as well as its capabilities for hydraulic applications it is also an oil of sorts, so it lubricates the moving parts in an auto gearbox or PAS rack. Probably.

 

Oilman would have a more detailed explanation - but definitely do not use brake fluid in the PAS; anymore than you'd pour it into an auto transmission!!
