Due to boiling my brake fluid on the track, I am thinking about putting in Mutol 600 fluid. On their website they say it must be changed every other race because it absorbs moisture. Is this true? So after every second event I have to go back to the Dodge dealer and spend god knows how much to get this done. Any insight would be greatly appreciated.

All brake fluid,save for sillicon,absorb moisture.
It is why the WET BOILING POINT is more important than the dry boiling point.
Regular good quality brake fluid are usually at 300 degrees wet.
Motul 600 has a 421 degrees rating wet.

It is alway safer to change your brake fluid often.
If you don't want to go to the dealer,you have 2 solutions.

Buy a Mityvac and bleed the brake yourself.

Use a turkey blaster and remove almost(don't uncover the holes at the bottom)all the fluid in the master cylinder,do it before you go to the track and a 2nd time after 1 session.

Think about Castrol SRF.EXPENSIVE.$70.00 per litre.Has a wet boiling point of over 500F.NO need to change it all the time.Expensive at first but pays for itself in not havning to do a change as often? Bruce

We buy Castrol SRF at BSR Products - they have offices / warehouses in Charlotte, NC and Mira Loma. Toll Free Number is 800.700.2350 They have been pretty cost competitive on fluids and ship right away. SRF is NOT the same as that other stuff. SRF is the best brake fluid out there - bar none. We still bleed after every event, only we just get the little bit of discolored fluid out of the calipers and do NOT have to flush entire system. We have NEVER had any brake fade. it's not cheap - but I think stopping is important.

Bleeding your brakes is a simple, brainless process once you know how to do it properly. It only takes one person plus a pressure bleeder. See your Viper service manual for part numbers.

Get in the habit of bleeding your brakes once per day at any track event. Some seriopus racers do it once every run session.

Don't waste your money on Castrol. Liter for liter it is nearly 5 times more expensive than Motul 600. When you bleed brakes often, you're gonna use alot of either one.

Luc,

I've surfed the MityVac web site in my search for a decent brake bleeding tool not long ago. Is this unit decent? Just for bleeding the lines, not for removing fluid from the reservoir, right?

I guess we have a variety of opinions here, don't we? Here's why we use Castrol... Its a unique formula that is less hygroscopic than any other fluid - it absorbs less water. Therefore, even when it has absorbed water its boiling point is still SIGNIFICANTLY higher than any other fluids wet BP. We don't like to work on our cars at the track. We don't have a mechanic that accompanies us. Any work we do - we do ourselves - its expensive for us to run 2 cars, so in order to keep costs down, we do our own work. We believe track time is for driving and prep and maintenance are done at home. So, jacking up the car, pulling all four wheels and bleeding the brakes at the track is not my idea of a good time - especially when either Henry and I are usually on the track every other session. While we may end up changing front brake pads, its just one less thing we have to do.

We ran three full days at VIR this year with no fade whatsoever. We did not bleed brakes during the event. So yes, the Castrol is about 3 - 4 times more expensive, but we did not bleed for three days. To us, that is not a waste. I will also say that running the Viper with the stock brake system, no true cooling ducts and track pads generate a TON of heat - so this may be the most severe test of brake fluids.

So, its up to you - I think using the SRF buys you something. If you want to bleed every day or (yikes) after every run, then don't bother with the SRF...

Michael,

The Mityvac is a very good unit.
Get the model with a vaccum gauge on it.
You can use it for bleeding,removing fluid from anything including the master cylinder and for vaccum check/leaks.

Regarding Motul versus Castrol SFR

Whatever fluids you use, the most important thing is to change it often.
Even if a fluid has a very high wet boilling point it is still a bad idea to have moisture in your braking system since water will corrode a lot of the components.

There is on the market a "Moisture Test Kit" that consist of stips of special paper that you put in the fluid and as in a PH kit,the color change depending on moisture content.

Considering you may run at speeds of over 150 MPH, bleeding your brakes after every event with a $8.00 bottle of Motul is cheap insurance of stopping when you need to stop.

I think the most overlooked benefit of the Motul 600 is that everybody has it and it's easy to find. Every motorcycle shop has it and if you're at the track and run low, somebody is bound to have some. You can't mix brake fluid so if you run low and have a rare fluid you'll be less likely to bleed your system.

You can get a set of brake "bleeder" valves. I think SVSi had stainless ones, but if not let me know, the place they produce them at is a few minutes from my house.

All you do is replace the current ****** with the bleeders, and then you can do your brakes on a daily basis if you like. I love them, and my wife likes the fact that she no longer has to do the brake pumping. Anyway, it saves you a lot of $$$ and it makes doing them as easy as possible.
