Hi i have just brought a 2004 wrx awd 2.0 turbo only engine mod is dump valve running standard brakes. i need to top the brake fluid up only a small amount its currently just above the min line but am unsure what Dot to use the cap says use only Dot3 but this seems not to be available and not sure what it currently has in any either any advice would be most appreciated thanks Steve

 

Hi
You can top it up with Dot 4 , if the level has dropped it will be an indication that the pads are wearing , as the pads wear the pistons will come further out of the calipers , which uses more fluid from the reservoir , you need to watch out as if you refill it back up , and then change the pads , when you push the pistons back into the calipers the fluid will go back into the reservoir and overflow and drip down your engine bay.

You should be able to see the meat left on the pads to give you an idea how worn they are

Hope this helps

Cheers Ian

thanks for the advice pads are due for a change soon but was thinking of flushing the fluid when they are done and refilling with somthing like dot 5.1 performace fluid thanks steve

 

HI
Yes if your flushing it through Dot 5.1 is a better option , I only said about dot 4 as you were asking about a small top up

I can supply you Dot 5.1 at £9.50 a litre which is enough to do the whole system and have a little left over
Check out the deals I have on with discs and pads when your ready

Cheers Ian

 

Dot 5.1 is definitely the best option and tyhat is a good price.
