Motul DOT 5.1 Brake Fluid
Is anyone running this fluid? If so, have you run into any problems with it, etc.
Long life 100% Synthetic Fluid DOT 5.1 Non-silicone base
MOTUL DOT 5.1 Brake Fluid
Meets DOT 5.1, DOT 4 AND DOT 3 manufacturer's recommendations. Fluidity specially designed for anti-locking brake system (ABS).
The high wet boiling point is 185 degrees C and 365 degrees F, which is superior to DOT 4 and DOT 3 brake fluids. Brake fluids have the properties to absorb humidity contained in the air, which reduces their boiling points and consequently, their performance. The wet boiling point is representative of the fluid after one year of use.
Specially designed for anti-lock brake systems. The viscosity (820 centipoises at -40 degrees C / -40 degrees F) lower than DOT 4 (up to 1800 cp) and DOT 3 (up to 1500 cp) brake fluids, allows an easier fluid circulation in micro-valves of anti-locking systems. Perfectly neutral with seals used in braking systems. Anti-corrosion.
Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
Performance Standards: FMVSS 116 DOT 5.1 NON-SILICONE BASE, DOT 3 AND DOT 4. SAE J 1703

Dont hold me to this but im pretty sure our manuel says dot 3 and 4 only and specifically says dont use dont dot 5. It might not be 5 but there is one it specificlly says dont use and im pretty sure its the 5.

Trackruner228,
DOT 5.1 is not the same thing as DOT 5.
DOT 3, 4, and 5.1 are polyethylene glycol-based fluids while DOT 5 is a silicon based fluid. Also DOT 3, 4, and 5.1 are hygroscopic while DOT 5 is not hygroscopic.
A hygroscopic fluid is one that simply absorbs water from the atmosphere.
DOT 3, 4, and 5.1 brake fluids are hygroscopic and thereby will readily absorb water. It is important that the brake fluid does absorb water and spread it out evenly through the system so that the water does not pool and cause corrosion in the brake lines which as we know can lead to brake failure.
Using a hygroscopic fluid reduces its boiling point which diminishes its performance. This is a problem for race cars, etc. but us TL guys should have no problem.
So stay away from DOT 5, but DOT 3, 4, and 5.1 are fine.
Thanks.

that fluid is WAY OVER KILL for these cars, way over kill, your wasting your money. i use motul rbf600 in my crotch rocket but that generates alot more heat in the braking system and the bike see's lots of hard riding. unless your a track day guy or racer, dot4 should be good enough for ya.

fsttyms1,
I did a search yesterday and I read about your deep hate about the Axxis Ultimate pads.
I am in the process of modifying my brake system. Will be changing out the rotors, pads, fluid, and lines.
I was talking to one of the guys at StopTech and gleaning some info and he told me the Ultimates are the "ultimate" (no pun intended) street pad. Stoptech runs these pads as standard items on their big brake kits. I also learned that some top level autocross drivers prefer them for their performance when dead cold.
Why do you dislike them so much? I know they are very dusty and can be slightly loud but their bite is incredible from what I have read. Did you bed them in properly? I know that a proper bedding in process is needed for these pads to work at their best.
What pads are the ultimate street pads in your opinon?

Most of us prefer EBC (green and red) Satisfied GS and Hawks upper levels (hps and hp plus).
The best pads in my opinion would be the green stuff or Satisfied.
Also what are you looking to do? If you never auto x or anything like that then Satisfied Pro Ceramic Pads would work as well.
I personally dont like hawks as well due to their high po street pads dont last as long

fsttyms1,
Thanks for the reply.
I was told about the autocross drivers using the Ultimates by the StopTech rep. I cannot confirm if its true or not.
My car is a street driven car. It is not a daily but when it is used it is driven extremely hard. Primarily in roads that have a lot of twisties & straights combined. So I need a well balanced pad that can handle anything I throw at it, whenever I throw at it. I am not worried about pad wear, rotor wear, dust, etc. I just want the best street pads possible. When I told the rep my needs, he proceeded to recommend the Ultimates.
I am running the OEM rotors and pads which have not suited my needs. I had some scary incidents at 120 mph and feel very unconfident with my brakes.
I was planning on going the following route. Some will say it is overkill but if it takes overkill for me to be supremely confident in the braking system, then so be it.
- StopTech slotted rotors. (F & R)
- Bleed brakes & refill using Motul DOT 5.1
- Goodridge SS brake lines.
- Axxis Ultimate pads. (F & R)
I have heard some good stuff about the Hawk HP Plus. Have you tried them?
Thanks for the reply.

You will care about pad wear and rotor wear when your replacing them every year.

fsttyms1,
You make some valid points. I appreciate your honest responses.
The only companies that make a BBK for the second gen TL are Rotora and Brembo, right?
Thanks.

Yes that i know of. Rotora brakes BBK and regular slotted rotors are very good brakes as well.
