Brake Fluid

[251am]

 '01 GSXR resevoir cap says DOT 4. Found some Bel Ray DOT 4 Plus. Can this stuff be used? Called three area shops-techs did not know for sure. Manual does not specify. Local aftermarket shop cannot order straight DOT 4, and only carry the 4 plus. All I know for sure is that DOT 5 is a no-no. Anyone? TIA

DOT 3,4, and 5.1 are all compatible. When I change to another brand or type of brake fluid, I flush through enough to make sure all the old fluid is gone.

BTW if you wnat the best, try Castrol SRF.

Thanks Brian-next flush I'll try the Castrol. Back to the Mighty Vac.

Let me guess Todd, you went to Foxy's.  ;D Personally I wouldnt let those guys put air in a tire.

If you are indeed going to try the Castrol SRF, be prepared for sticker shock. I get it at Pegasus in New Berlin, WI for $72/liter.

Yeah, I went to Foxy's. I think they might know Harley baggers, sometimes, but the techs at Shogren, Engelhardt, and one other shop had no idea for sure. They all knew what NOT to do, but didn't seem to know if Bel-Ray 4 Plus was compatible with what was a Suzuki product already in the resevoir. I shoulda just called Whizzenat, right off the bat.
  Holy cats man $72 a liter????!!!!! What's the scoop on this stuff? I'll do some research. Does it last longer-like a couple of years? Is it the Viagra for my master cylinder? Is it synthetic or mineral based or a blend? Anyway, wow, that's spendy fluid.

THey dont know baggers either. The only thing they know is what stunts are what.


In 2000 I had a new chain installed on my YZF by them (the countershaft nut was no coming off for me). WHen I got the bike back, the shifter was so damn low I had to adjust it there. THey looked befuddled when I said the shifter was too low. When I got home, I had to replace the rear brake pads then next weekend. Went to take the caliper bolts out and ALL the threads in the aluminum bracket were stripped out. Looked at the bolts and they had IMPACT wrench marks. At the time, I didnt own air tools nor any impact drivers. So after that, f-em. Not only that, their parts people and store mgr there are a$$hats.

If you want some good stuff at a more normal price, try Motul RBF(?)600.

The SRF has a higher wet boiling point than most fluids dry boiling point.

Agreed, RBF600 in an excellent fluid.

That may be true - but have you ever boiled your brakes in a race?  Or heard of anyone who has?  

[Steviebee]

I have boiled the fluid many times.   Thats why the brakes get spongy (sometimes).

We all dont have those little SV's.
