The Best Since Slice Bread 🍞
Being the owner of 2013 F150 3.5L Ecoboost with a 2 inch suspension lift upgrade with IVD Struts, 35x12.50r18 inch tires, Rear Nitro Shock Absorbers, and etcetera. You will need the best of the best DOT 4 Brake Fluid for vehicles in the weight range of 7200 pounds. The braking power of this Motul 660 is unparalleled to the standard stock DOT 4 brake fluid from your local auto parts store, heck any standard regular brake fluid pales in comparison to Motul 660. It's not overkill by any stretch of the imagination. Pay the extra dollars for high performance brake fluid and know you're in good hands. It shines even better in the winter snow storm with icy roads. I've recently used Motul 660 in my parent's 2018 Toyota Highlander 3.5L XLE and the braking experience was night and day plus the factory stock brake fluid was at 80,500 miles of usage so believe me when I say "it was darker than night". So yeah. Enjoy 😉 Cheers 🍻

Great upgrade for brake fluid
Great quality product. I drained out and replaced the brake fluid on my 2017 R6 with the Motul RBF660 fluid. Made sure to flush front and rear lines and fill them completely with the Motul brake fluid. Temp range on the fluid is great and it gives me confidence I can brake hard and not have to worry about my fluid failing.

Been using Motul brake fluid in all my cars
Motul makes higher boiling point brake fluids (racing) and any hard driving scenarios possibly like mountain driving that can tax the rotors and calipers with excessive heat. When i replace my fluid with these, it might be in my mind but the pedal feels a little better so i do replace every time i do my brake pads. Great stuff.

Ultra high performance fluid!
Very good Brake fluid! Extremely high boiling point! Make sure to bleed brakes and buy at least 3 bottles. It’s pricey but well worth it especially if you heat your brake pads a lot.

Snowmobile Racing
Unlike Sport bikes, quads and dirt bikes snowmobiles weigh more and only have one caliper and rotor to stop you. This is fine for average riders but when racing these brakes build up unreal amounts of heat in a couple corners. (Will literally melt my boot to the brake guard that's right next to my foot). Even with these conditions however i feel very little brake fade even on some of the tightest sections of the tracks. While with brand new dot 4 fluid that youd buy from an auto parts store would only last maybe 3 laps on a ice oval before boiling this fluid seems to never boil. I do replace it right before every race however to avoid any boiling.

Good feel and tech specs
Tech specs are great and from an initial check the brake levers on my motorcycle feel great after switching from the standard DOT4 to the RBF 660.

Huge improvement over stock fluid.
I purchased this fluid for my Focus ST. I regularly race my car at autocross, time attack, and some track days. I read good things about this fluid so I pulled the trigger, and I couldn't be happier. Unlike with the stock fluid, there is zero fade during 7-8/10 driving and barely and fade when driving at 10/10. Worth noting-- I also replaced the stock pads with Hawk Performance pads at the same time as the fluid. I've driven my car on track for over 10 minutes at a time with speeds nearing 120 mph and pedal feel held up. It's a bit pricey, but not unreasonable.

Absolutely amazing, no sign of brake fade under repeated use and hard driving.

J'ai choisi sur liquide de frein pour un usage sur circuit. Très bon produit avec des températures d'utilisation élevé. Grace a ce liquide j'ai obtenu une excellente endurance de freinage tout au long de la journée. Pour le tarif je m'attendais cependant a le recevoir plus rapidement, car 15 jours après avoir passé commande. Ce fut long. Pour 5€ de plus le bidon (18€90 au lieu de 14€30), je l'avais le lendemain au magasin proche de mon domicile.
