I looked in the FAQ & didn't see this listed....I'm going to do a brake job & upgrade pads, rotors, and lines. I will need some new brake fluid. What type is recommended for KLR's? Any high temp upgrades available?

DOT 3 or 4 will do the job. I use DOT 4 synthetic, can't remember the brand, it's one of the major brands though. Here's a brief write up. There are others with much more detail. http://www.shotimes.com/SHO3brakefluid.html "Lets look at what the DOT ratings mean. The table below shows the MINIMUM wet and dry boiling points for DOT 2, 3, 4, and 5 brake fluid in degrees fahrenheit. DOT2 DOT3 DOT4 DOT5 Dry Boiling point 374 401 446 500 Wet boiling point 284 311 356 The DOT 2 spec is for drum brakes and is obsolete." Steve In Niceville

The highest temp DOT-4 fluids I know of are Valvoline Sythetic (or"Synthpower" or something like that) and Castrol LMA. Mark

FYI anything over the minimum specified amount would bve fine. IE: if it recommends dot 3 then dot 4 or 5 will work just fine

NO! DOT 5 is NOT compatible with any other kind of fluid and requires a specially constructed braking system to use it. If you contaminate a standard system with DOT 5 it is very, very difficult to clean it completely and go back to DOT 3 or DOT 4. -- Blake Sobiloff San Jose, CA (USA) [Non-text portions of this message have been removed]

Right!!! No DOT5. DOT 3 or 4 only.

Motul RBF600: Has the highest dry and wet boiling points of any brake fluid on the market. It's DOT 4, which is fine for the KLR's braking system. (Relatively) expensive and can be hard to find locally. Check motorcycle and high performance foreign car parts shops. Castrol GT LMA: Resists moisture well (for brake fluid) and has fine dry and wet boiling points. It's also DOT 4, so it works just fine in the KLR's braking system. (Relatively) inexpensive and easy to find at most auto parts stores. Unfortunately, it tends to come in large bottles, meaning that you'll waste a lot if you're only doing one bike. Change your brake fluid EVERY year, and ALWAYS use a new bottle. -- Blake Sobiloff http://www.sobiloff.com/> San Jose, CA (USA) [Non-text portions of this message have been removed]

...and DOT 5 is based on silicone, which is incompatible with all braking systems not specifically designed for it, and it can not be mixed with any other DOT-ratings, so just say "no" to DOT 5. Don't even think about it.

Do not use DOT 5 brake fluid. AS previous posts said, it is not compatible with other fluids. Additional issues are that it has been known to turn into a jelly which is difficult/impossible to remove. No time to go into detail but in short: -Regular brake fluids absorb moisture which the military thought was a bad idea since the moisture tends to drop out into lower areas during temperature changes. - This moisture drop out, combined with copper deposits in the system, create damaging corrosion (usually in the form of pitting) in the bottom of wheel cylinders, calipers and master cylinders. -It was decided to develop a non-hygroscopic (non-water absorbing) brake fluid to avoid the problem with vehicles in storage by the military. - Problems, turning to jelly, incompatibility with other fluids and......you guessed! Since it doesn't absorb water, the water which enters the system due to air cycling and condensation is not removed by brake fluid changes, stays behind and corrodes. People tend to believe that the higher the DOT number, the better the brake fluid. This is true up to DOT 4 but not for DOT 5. Gotta go, Norm [Non-text portions of this message have been removed]

Then if you are not already confused there is DOT 5.1. DOT 5.1, like DOT 3 and DOT 4, is a polyethylene glycol-based fluid (contrasted with DOT 5 which is silicone-based). Fluids such as DOT 5.1 are hygroscopic and will absorb water from the atmosphere. This degrades the fluid's performance by drastically reducing its boiling point. In a passenger car this is not much of an issue, but can be of serious concerns in racecars or motorcycles. As of 2006, most cars produced in the U.S. use DOT 3 brake fluid. Boiling points Minimal boiling points for these specifications are as follows: Boiling Point Ranges Dry Boiling Point Wet Boiling Point DOT 3 205 C (401 F) 140 C (284 F) DOT 4 230 C (446 F) 155 C (311 F) DOT 5 260 C (500 F) 180 C (356 F) DOT 5.1 270 C (518 F) 191 C (375 F) Just thought I'd throw that in.
