and still have a few questions. I see use DOT3 or DOT4 but not DOT5. Opinions vary so I would like to ask anew. Im putting the Rotora BBK and new Rotora slotted rotors and pads on the rear. I would think this is a good time to completely flush the lines and put in new fluid. Just looking for suggestions guys.

 

DOT5 fluid does not absorb water since it's silicon based.

DOT4 can withstand higher temperatures than DOT3 fluid can, so in that respect it's more heavy duty/performance oriented. most cars come with DOT3 but if you want to flush and go to DOT4 i suppose it's really a 'peace of mind' issue since most cars will not experience braking temperatures that high. if they're the same price i would say to upgrade, if not then i would stick with DOT3.

Use the Genuine Honda DOT3 fluid. I know, I know, its a bit over priced. But Honda engineers their cars to last forever, and the parts are all designed to be used with their fluid. My last Accord went 272,000 miles before failing inspection for body rust. Always used Honda fluids and always will.

 

I had stock fluid in there with my Rotora BBK and rear slotted rotors, and the fluid boiled when I did a 100-20 full force stop. I switched to ATE Super Blue fluid.

By the way, DOT 5 silicon-based fluid can eat up the seals in the master cylinder, therefore not recommended in ordinary cars.

 

dot 3 or 4 is preference, cant use dot 5 on a street car like satinsilvertyps said. its a race only application.

 

holy shit. i think i'll go to dot4.

DOT 4's boiling point is higher than DOT 3, but not all that much higher. If you boiled the fluid with only one 100 to 20 stop, its a braking system problem, not a brake fluid one. You might want to route some cooling air to the brakes to keep boiling to a minimum.

I use DOT 4 in my Camaro and never boiled the fluid, even with multiple 100+ mph to 0 stops in quick succession (Baer Track kit). The car stops better the hotter the brakes get, which is a bit strange to normal drivers.

 

You should not use DOT 5 in your car unless you want to screw up the braking system.

You need to use either Dot 3 or Dot 4 compatable brake fluids. Below is a comparison link for your convenience.

I use and recommend Vavoline Synthetic brake fluid. The Vavoline has a higher boiling point than most of the other Dot 3 & 4 brake fluids. It is also easy to find.

 

So why is it that it hasn't faded/boiled since I've switched to ATE Super Blue? The brake fluid is the only thing I've changed, and the problem went away.

 

Exactly the reason I was asking this question in the first place.
