While the two products share some similarities, they still have several key differences as below: Purpose When heated to 270 degrees Celsius (518 degrees Fahrenheit), Castrol SRF is at a higher temperature than Motul 660, which is set at 204 degrees Celsius (399 degrees Fahrenheit). However, if the brake is flushed regularly, this wet boiling point is a moot matter. DOT stands for department of transportation and often provides specifications and safety regulations for car part manufacturers to adhere by. So, the performance of Motul 600 is better in colder conditions meanwhile Motul 660 will perform much better during higher temperatures. Contrasting brake fluids

This product is a popular choice among professional endurance race drivers and car enthusiasts to flush their brake fluid for the best possible performance from their engines. Sometimes, the Motul 600 boiling point is exceptionally high without water. In contrast, Castrol SRF also has these standards: temperature of 590° F, which is 310°C. Motul 600 may be the best brake fluid if you want them to have a higher boiling point after drying. Price Point

About Klarna

Motul 600 has higher viscosity comparatively at -40 o C which makes it cut above its peer. Therefore, it will perform more dominantly during such conditions. Motul 660, which has lower viscosity in frosty conditions, will perform superiorly because of its greater viscosity at elevated temperatures that is at 100 o C. For racers, having a waterless boiling point is an essential feature. This is the temperature of the braking fluid when it is uncontaminated and uncovered.

No-load funds that are primarily available to clients of PH&N Investment Services prior to January 9, 2017. These funds pay management fees to RBC GAM. A portion of the management fee is paid by RBC GAM as a trailing commission to the dealer. The trailing commission is typically lower than other series. Compared to Motul 660, Castrol SRF is superior. This less frequent replacement is a significant factor in lowering expenses. In contrast, if you use conventional brake fluid with Castrol SRF, this mistake can reduce the quality of this Castrol SRF brake fluid. That’s why, before refilling with Castrol SRF, you should drain the conventional brake fluid very well.Even, both are equally reliable and come from the same brand. So Motul 600 and 660 are close brothers and if you ever use Motul 600, then the 660 will feel similar. That means you can put the RF-650 for longer without doing a full flush. Water in the system means it will boil you down with a spongy brake pedal. The Endless RF-650 seems to be another trendy option. Still, it has a high wet boiling point but not as high as SRF. Motul 5.1 Vs. RBF 600 https://cdn.opieoils.co.uk/images/variants/large/motul/motul-rbf-660-factory-line-fully-synthetic-dot-4-racing-brake-clutch-fluid-500ml-1.jpg

Therefore, choosing the right one between these two liquids takes a lot of work. Overall, if you find a brake fluid that can tolerate high temperatures, go with Motul RBF 600. Nevertheless, if you want different consistency in your brake system, the 660 might be your best choice. Motul RBF 600 Vs 700: The DOT 5 fluid contains silicone as its primary constituent and it cannot be assorted with any other fluid which comprises glycol. No-load funds available to investors who have a fee-based account. Instead of paying for advice and other services via a trailing commission, investors pay ongoing account fees to their dealer separately. These funds pay management fees to RBC GAM. Series FT units are designed for investors wishing to draw regular tax-efficient income from their non-registered investments and aims to pay consistent distributions each month. MOTUL RBF 660's technical capabilities are superior to those of conventional DOT 3, 4 and 5.1 fluids (except for the -40°C viscosity of DOT 5.1). Motul RBF 600 is a DOT 4 brake fluid capable of exceeding DOT 3 standards. These fluids can be used for all kinds of braking systems except the one which uses silicon-based fluid. It has a quite high dry boiling point plus its wet boiling is also on the higher side. During chilly conditions, the performance of this fluid is also very impressive because of its high viscosity. The long intervals of replacement further make it a very attractive choice for the consumers.

RBF600 will need more frequent flushing. Furthermore, Rbf 600 contains a higher boiling point. It’s an incredible race fluid, but it tends to absorb more water and will require more frequent bleeding. https://cdn.opieoils.co.uk/images/variants/icon/motul/motul-rbf-660-factory-line-fully-synthetic-dot-4-racing-brake-clutch-fluid-500ml-2.jpg Provides the highest performance under racing conditions, where braking systems must operate at very high temperatures
