Title: Brake Fluid & Trans Fluid Post by: SteveW on February 27, 2009, 08:59:30 am I'm going to fill up the brake system in the next day or so with fluid, I'm guessing I should run DOT 5.1 ? How much fluid will I need to fill the system from scratch?!
Also what trans fluid are you guys using? Thanks Steve Title: Re: Brake Fluid & Trans Fluid Post by: Joe_G on February 27, 2009, 09:32:21 am Steve, you could try using this for your brakes http://www.frost.co.uk/item_Detail.asp?productID=8658&frostProductName=Silicone+Fluid+%281+litre%29&catID=14&subCatID=&FrostCat=Brakes&FrostSubcat= (http://www.frost.co.uk/item_Detail.asp?productID=8658&frostProductName=Silicone+Fluid+%281+litre%29&catID=14&subCatID=&FrostCat=Brakes&FrostSubcat=) it doesn't harm your paint and doesn't need changing.
Title: Re: Brake Fluid & Trans Fluid Post by: SteveW on February 27, 2009, 09:52:04 am Cool that looks good, so that's DOT 5 which is silicone based then. This fluid's boiling point is 260°C, i'm guessing that would be ok for drag racing as we're not on the brakes for long periods..

Also what trans fluid are you guys using? Thanks Steve I use a regular 75-90 semi synthetic, again no problem. Bernie Title: Re: Brake Fluid & Trans Fluid Post by: SteveW on February 28, 2009, 00:03:38 am Joe, it's getting there, just sorting out the 'other details' now
I spoke to Chris Isaacs today who has manuals on the Strange brakes and it recommends to only use DOT 4 or DOT 5.1 but only of a glycol base not silicone. Because of the silicone based fluid not absorbing moisture, if any does get in the system then it sits on the calipers and damages them (I can't remember the exact wording it uses but its basically that..) I just picked up some ordinary synthetic DOT 4 so I'll try that. Thanks Steve Title: Re: Brake Fluid & Trans Fluid Post by: Bruce on February 28, 2009, 09:34:45 am . Because of the silicone based fluid not absorbing moisture, if any does get in the system then it sits on the calipers and damages them ..... That's the rhetoric the deniers always state. Since silicone juice doesn't absorb water from the air, it won't be in the calipers to corrode them.15+ years of the same silicone juice in my brake system. No problems at all, and it rains a LOT here. For a drag car that gets driven only in the dry, why would you worry about it?

Mercedes Brake fluid every year for brakes, because it's "available".

It rains a hell of a lot here too (and especially when your at the racetrack!) so I thought DOT 4 would be fine. Thanks for the advice everyone :) |
