    Dot 5.1 in the North Valley

    Other than buying the Avid brake fluid from a bike shop, are there any Motorcycle/Auto stores that carry DOT 5.1 brake fluid in the North Valley? I've tried Checker, CycleGear, and RideNow PowerSports in the Hwy 51 area with no luck.

    Any Suggestions?

    Jibro. Some Mercedes use it. Worse case check a dealer.

    I'd be curious to know too! I put some Dot 5 into someone's new Codes but was told by some shop guys that was a big no-no. Something about synthetic vs. nonsynthetic? So if we cannot find 5.1 anywhere, would substituting Dot 4 for Dot 5.1 be better than using Dot 5? I'm hoping someone in the know will spout some wisdom on the subject...

    Dot 3 , 4 , 5.1 is all compatible .....but if you really want a good brake fluid that will not fade use Motul high temp racing fluid , its rated as a 600 degree fluid but I see temps in excess of 1400 degrees come off superbike systems and 900 to 1200 come of moto systems and the Motul does not fade or change at all.

    I was easily fading the standard 5.1 in my avids ...went to Motul and no more problem

    I just picked up some 5.1 from NAPA two weeks ago or so ago for a truck I was overhauling the braking system on ........just make sure you do not ever use 5.0 silicone fluid ....this stuff is some of the worst fluid I have ever tried to use

    I think most NAPA or Checker stores carry it. If not, Checker could probably have it in a day or two if you ordered it. You can buy the Motul- .5 liter for $8 on amazon.

    KK: You CANNOT sub 5.0 for 5.1. Most manufacturers allow DOT 4 as a 5.1 sub.

    The dot 5 silicone fluid came around for hot rod guys that did not want the fluid to eat the paint if they ever got any on the paint , -----stupid i know but that was its claim to fame .

    oils come in some different base categories ,....the quick and dirty explanation is --------you have "Petroleum" ......"Caster"..........".Vegetable"........".Mineral "

    Brake fluid in most "English / American systems are "Vegetable fluid only systems .

    The dot 3,4,5.1 are all Vegetable base brake fluids and are all compatible.

    The strange dot 5.0 is a hybird design silicone base that is supposed to work with in a vegetable base system .......but it DOES NOT and really should not ever be used as a brake fluid at all .

    Now this is just a down and dirty simple explanation .......I could right a book on oils , fluids and the like but it gets really boring really quick .

    And do not ever mix ---Petroleum ...Caster.....Vegetable.....Mineral ever in any form other than salad dressing ......

    I think the Motul RBF600 is the stuff I'm looking for. Brand new Codes and they're as soft as Doo-doo. Fade like Doo-doo too. If all the 5.1 stuff is the same a racing DOT 4 is probably the way to go. I've been gaining some more mass these days and need all the help I can get to keep the brake power firm and even.

    So.... would flushing the 5.1 from the lines with 4 clean it out enough or should I disassemble everything thing and really wash all the rubber bits in the levers and calipers? And if I did that, what do I wash with? Geeez, for being a scientist and a self-proclaimed good bike mechanic, I sure am a dolt about hydraulic brakes! But my moto has always been "live and learn" Sometimes the learning comes with a price

    Yes the Motul 600 is what you are looking for , I have some if you can't find some soon enough .

    I generally get mine from "SouthWest Dist" in PHX , I have seen it at "Cycle Gear "
    and the Apache Honda stores , ......and you can order it from "RockyMountain Cycle"

    It's been so long since I had my CBRs fluid changed I can't remember for sure but I'm pretty sure that's what I had put in my lines. Hadn't thought about putting it in a bicycle's lines but next time I need anything done with my brakes I'll have that fluid swapped and bled.

    No, you do not have to breakdown all the pieces and parts. Yes, you do have to remove as much of the old fluid as possible, otherwise the new bleed will only be as good as the old fluid's temp rating. All cleaning and clean-up should be done with 90% Rubbing Alcohol.

    You can also order online from lots of MX stores, here is a couple of links.

    What is the life span of Motul 600 in the bottle after being opened? According to Avid DOT fluid lasts only 48 hours after a bottle being opened before it absorbs to much moisture thus breaking down the fluid. If you create a good secondary seal can store it for maybe 2 weeks.

    I've never had a problem finding it up in hickville Prescott, so I doubt you would in the valley. Yes, it has a shelf-life. If I don't use the entire bottle at once, I throw it away. It absorbs moisture from the atmosphere, doesn't necessarily "break it down", but it lowers the boiling point significantly.

    I'm off to the moto store today to replace the "factory" fluid in my Avid Exclir's. I'm having major brake fade in and fade out on most longer descents. Originally, these brakes worked just fine, but now it sure seems like most of the new Avid's need a brake fluid flush within 6 months of use.
    I will give a report on the prognosis. I have a trip to the Alps coming up and I have been warned to have my bike's brakes in best ever working condition. We are talking many thousands of meters of descents (and some major climbing too) per day. I'm also taking an extra set of brake pads. I'm skeered!
    There is a big difference between ripping and skidding.

    Any brake fluid should only be opened before using and any left in the bottle should be discarded and not used at all.

    Brake fluid should be changed very often , I change mine in my trucks cars and bicycles every 6 months .

    In my race vehicles or race moto bikes I change it out all the time

    You are correct , about the 6 month mark the old brake fluid just looses any of its tempature threshold, ....nothing like new fresh high temp fluid with fresh pads .....its something thats is really overlooked by most people on their vehicles , and it sure can get your attention when it starts to go !!

    Hmm. I've been bleeding my juicies with the silicone stuff for a while. Its pretty (pink), doesnt take on air and doesnt burn my hands. Seems to be working fine, although I have one sticky rear brake on the f-bird.
