Megabusa: Brakes and Brake Fluid

[dinanminicooper]

Hello all! As the new owner of Hank's Megabusa, I am trying to get the car sorted for the track.

 

As such, am curious if anyone has any suggestions for track pads and specs with the AP Racing 4 pots up front, as well as stock Megabusa calipers in back.

 

Also, does anyone know capacity of the fluid reservoirs for brake fluid? There are two reservoirs for front and rear. Am going to flush and refill fluid and intend to use ATE Super Typ 200 (Amber) fluid. Any issues there? Or should I run the Motul 600 stuff instead? I will likely buy 2 liters to be safe.

 

I've run the ATE Super Blue on my MINI Cooper S street/race car for the last 2 years and have never had a soft pedal issue so I am inclined to go that route.

 

Thanks!

I'm a big fan of Super Blue and Type 200. They are identical fluids, just coloured different.

 

Makes maintenance easy. Swap fluids when doing a complete flush and refill. Bleed until the colour changes. Done.

I use the Motul RBF which has pretty good dry and wet temperature ratings yet is still affordable at about $16/pint. The more serious racers use the Castrol SRF racing brake fluid, and at around $75/quart, it's a serious investment. As the previous post stated, the ATE Blue or Gold are very popular fluids for the lighter cars and autoX. I think their rating is a bit less than the others but so is the price, and unless you are doing some very serious and long track events, may not need more. Generally speaking, any track events less than 30 minutes and less than 140 mph won't test the brake flluid's capacity to prevent a boil over. However, no worse feeling than coming into a corner at full speed and having the brake pedal bottom out..............makes you get very religious very quickly.

What DOT number are these brake fluids (3, 4, or 5)

I changed my '80 Dodge Colt over to DOT 5 (silicone) fluid and never had to change any system parts other than front pads. I traded the car with 212k miles.

It does not attract moisture but it is not compatible with some seals.
