For all types of hydraulic brake and clutch actuators requiring non silicone synthetic fluid.

Very high dry boiling point of 617F (325C) and a wet boiling point of 400F (204C).

For all types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid.

Specially designed to resist extreme temperature generated by racing brakes (carbon and ceramic) only allowing a minimal air entrance for brake cooling. 

A brilliant upgrade on standard brake fluid for any track-bred vehicle, Motul RBF 660 goes well beyond all conventional DOT 3, 4 and DOT 5.1 standards, and goes one step further than Motul RBF 600 by minimising air entrance on your vehicle's brakes, stopping your brakes from going cool and promoting aerodynamic efficiency.

Motul's RBF Brake Fluid range is their ultimate high-performance brake fluid formula, utilizing their vast range of 100% Synthetic technologies to ensure unsurpassed boiling points and the resistance of extreme braking temperatures in all race conditions.

Motul RBF is one of the most popular brake fluid ranges used in Australian motorsport.

500ML Bottle

Extreme thermal resistance and stability :
Very high boiling point (325°C / 617°F), superior to conventional DOT 5.1 non silicone base / DOT 5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini).
Enables effective brake even in extreme conditions. 
Better aerodynamic performance by reducing air entrance for brake cooling on cars.

Efficient when rainy :
Very high wet boiling point (205°C / 401°F) superior to conventional DOT 5.1 non-silicone base fluid (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini) enables to keep efficient braking while rainy. 
Brake fluids tend to absorb humidity from the air, which reduce boiling point and increase the risk to get to “vapor lock” phenomena. 
The wet boiling point is measured by humidifying the product with about 3.5 % of water.

Exceeding the DOT standards of dry boiling point while ensuring rubber seal compatibility, Motul brake fluid delivers performance you can trust. 

Before use always refer to the owner manual or handbook of the vehicle.

Please note RBF 660 is a high maintenance product. 
It is very hydroscopic and requires brakes to be bled regularly. For a high performance weekend drive we would strongly reccomend the Motul 600 over the 660. If you are running big brakes  or ceramic discs and pads and are used to doing regular changes and bleeds, then by all means the 660 will be for you.

The synergies between Motul and McLaren GT are evident: high performance,  
quality, prestige and a long, successful history in motorsport. Following a successful association in 2016 with McLaren GT customer race team, Garage 59, a newly announced partnership sees Motul become the approved lubricant supplier of McLaren GT and its customer teams. 

2016 was a successful debut year in the working relationship, with highlights including victory at the Bathurst 12 Hours in Australia, and a championship title in the Blancpain GT Series Endurance Cup.

The partnership will, from 2017, see Motul supporting six McLaren 650S GT3 models in the popular Blancpain Endurance Series and Blancpain Sprint Series – four entries in both championships from the British ‘Strakka Racing’ team – and two 570S GT4 entries in the British GT Championship with the ‘Black Bull Garage 59’ team.

Central to the deal is the technical relationship between the two companies, and products from Motul’s Motorsport Line range are now recommended to all new and existing customer teams. Among these products will be 300V Trophy 0W40 (engine oil), Gear 300 LS 75W90 (gear box oil) and RBF 660 (brake fluid).

 

Please note that due to it's hazard rating oil's cannot be sent via Australia Post, and must be sent via a courier.

Good spicy campy hockey
Format: Kindle
I really enjoyed the character development. Reading about their growth and dealing with individual issues made good entertainment. Some surprising twists that made the book even better. Really glad we didn't have to go down the angst road where the public got to damage the budding relationships.

Great read!
Format: Kindle
Wonderful characters with great humor, a bit of mystery and a strong silent grumpy Sentinel to stand with the leading lady. They make her stronger but she also makes them stronger. I love the dynamics and the way it played out. This was a fun read!. I received a free copy of this book via Booksprout and am voluntarily leaving a review.

June lives her life squarely in the NSFW zone...
Format: Kindle
June Wilder has embarked on the career of a lifetime-- the newest head physical trainer for NHL's Atlanta Reapers! She's relatively young for the position, not to mention female. In a male dominated sport, she's hoping to one day earn the trust and respect of the players, coaching staff and the organization.  What she doesn't expect is to be an equal participant in flirty banter and NSFW activities in her office with handsome Right Wing Rhett Lawson. She quickly finds that Team Captain Cole Thibault is a confident and  calming presence in her daily work activities-- and the man she goes on quite possibly the most perfect date with. Then there's Elias Nystrom, the Swedish Goalie who is quiet, HULKING in size, and downright frightens her-- with whom she shares a secret which could get her in hot water if discovered.  Each of these team members intrigues her. Each she has a relationship with that is not entirely permitted as their head physical trainer. As she gets to know each of them better, she's falling deeper for each of them. Will she successfully navigate through the season without losing not only her job but her heart?  What happens when each of the men find out about each other? Will she be asked to choose between them?  This book has everything I look for in a sinfully decadent read-- a strong, independent, and likable FMC; charming, protective, and sexy MMCs; a plot that is entertaining, well thought out and executes some unexpected twists; and has chemistry that explodes off of the pages. Once again author Cassie Cole has expertly achieved all of these things in her latest book "Hat Trick". I'm a big fan of the RH genre. Of all the authors I read, Cassie Cole is far and away my favorite to date. If you read this book, you will not be disappointed!

Hot enough to melt the ice rink
Format: Kindle
This was yet another great read by Cassie Cole. June has just started as the trainer for the Atlanta Reapers. Succeeding in this male dominated role is important to her, but the more she learns about these men the more she wonders if some things are worth risking everything for. As their trainer, the men are supposed to be off limits, but they can't deny the pull they each feel. The closer to Cole, Rhett & Elias she becomes the more she realizes that she may not be able to choose between them. Is it worth the risk to her career to continue to pursue a relationship with one of the men.... let alone the risk to all their careers if they would be open to consider a more unconventional relationship. Is love worth the risk? Read this steamy story to find out!. I received a free copy of this book via Booksprout and am voluntarily leaving a review.

Hat Trick (A Hockey Reverse Haven Romance)
Format: Kindle
I loved this book, what a trip! All the things a girl could want, plus getting Alice involved with their family. Nothing better than a lot of sex and love and a great sport, the baby sill be so spoiled when they have one, wow. Reverse harems are a favorite of mine. What a treat with this family, poly amorous it is. Interesting to the end. See you next time.
