Should be a high level performer.
It was recommended as a good performing brake fluid. Haven't used it long enough to say if it's really good but considering it's made for racing, I'm of the belief that's it's a very good product.

Great Product, shipping error
Great once I received the bottle. First package was empty. But the product is great, can’t beat it for dot4 fluid.

Awesome Brake Fluid
I have a 2013 Corvette Grand Sport that I used this in. One full day at an HDPE event in NJ and I had no problems; no brake fade, no pulsing, no overheating and the brake fluid looked very clean and like new. For the price this would be probably the second best brake fluid available, the next step up and you are paying big bucks. For me and the occasional HPDE track day or days, this works perfect. One final thought on this brake fluid... yes this is expensive, alot more expensive than going to the local store and buying off the shelf. But!!! These are your brakes you are dealing with, and if the fluid fails and you have no more brakes... IMHO this is the one place to not be cheap or save a few dollars.

Works great
I’ve used this fluid in my track car and Spec Miata racecar for years. Works great and have never had a fluid related brake issue. Very happy with this product

Best Value High Performance Brake Fluid
Dry boiling point is everything for a car that is driven hard, such as high performance track days. If the car is also a daily driver in a wet climate, you may need to flush and change Motul 600 more often than some other brake fluids, as all "normal" brake fluids are hydroscopic and absorb moisture from the air. On a car that sees the track often, you are probably changing it every year already, so no downside to Motul 600.

Why did you pick this product vs others?: Excellent product. Why not use the newt.

If you want the best
Excellent brake fluid, I ride steep mountain terrain as well as wide open "flowy" single track. My brakes take a beating and since I switched to this product I have had zero issues with brake fade! Buy a bottle and change it once or twice a season (more if your racing) and rest easy knowing you have the best product available in your brake lines. It seems like I use about a 1/4 of a bottle per service, that includes a complete service of the front and rear braking system as well as the hydraulic clutch.

Replaced all my brakes and clutch on my Goldwing. Should last till I get rid of the bike.

Motul is the heart and soul of my Nissan, I've never had anything else other than this brand, along with my Oil, I trust the brand to keep my car running healthy! I recently have to swap out the CSC in my 370, studded this in and it made a good difference! 1000x recommend!

Flushed my clutch fluid in my 370Z, used about half of this container, the clutch and slave system is rather small. After the flush, the clutch pedal feel was much smoother and with a lot less clutch noise when releasing the clutch while the transmission was in neutral. I would highly recommend this product!

The Motul DOT-4 makes a difference in my braking and clutch operation, better performace than other brand that I have used in the past in my motorcycles, a bit expensive but worth every penny, quality has a value.
