if I don't chance the BMC, then I don't need to bleed that right?

I quoted the shop manual. They only listed ONE method of bleeding the brakes.

How do you bleed the MC?

Same way as you bleed the brakes at the calipers.

I think only the 04, 05 have it?

Even easier if you have Russell Speed Bleeders. ;)

btw: the MC is self bleeding (high point; open to atmosphere).

Installing Power Slot rotors and Hawk HPS pads this weekend. Question: How much fluid does the system take? The reason I ask is I see online that there is 12oz... then 32oz, then a gallon. I really don't want to buy anymore than necessary for the job. Thanks in advance. Bill

32 oz will cover a full fluid swap with a good amount left over left over... if you're just change pads and rotors, you shouldn't lose that much fluid... I had enough left in the 32oz to change the fluid in my motorcycle too.

walmart had 4oz bottles of prestone DOT4 fluid which would cover that job. I would get 2 bottles if going that route...

If you are just changing pads and rotors you don't need to crack the hydraulic system. If you are just bleeding the brakes you can probably get by with half of a 16 oz bottle. If you are flushing the system with new fluid you can probably do it with a quart (32 oz)(liter) but might want some extra on hand in case you need more.

good call... i had some fluid spill out of the MC when pushing the caliper pistons back in... that is really the only way to lose fluid.

^ Yep. Always good to wrap a rag around the MC reservoir (cap ajar of course) when retracting the caliper pistons.

Thanks for the advice guys... Though I don't do any track racing, we are looking at flushing the system when we replace the rotors and pads. I also notice that Prestone makes a synthetic brake fluid. They say it is recommended for anti-lock brakes. Is there any advantage to this over regular Dot-3 fluid?

There are 4 types of brake fluid out there, DOT3, DOT4, DOT5, and DOT5.1. DOT3 and DOT4 are glycol ether based and are safe for the RX8. DOT5 is a silicone based fluid and not recommended for the RX8. DOT5.1 is a glycol ether based fluid and was an attempt by the DOT to undo the fuckup of DOT5. All brake fluids are synthetic. DOT4 and DOT3 can be mixed, DOT4 has a slightly higher boiling point. If the car is only seeing street use regulaar DOT3 or DOT4 fluid is fine. If you are tracking the car on road courses you may want to try somthing like ATE Super Blue racing fluid (DOT4). See Brake FAQ http://www.rx8club.com/showthread.php?t=167264 .

DOT 5.1 is best if you want ABS surround sound. ;) (couldn't resist)

Off topic, but I'm troubleshooting a sound I notice since upgrading to the Racing Brake BBK.

Is this sound you're referencing an audible "click" coming from each side when first depressing the brake pedal?

Thanks for clarifying! I just spent 20 minutes staring at my MC looking for that.

There's really no need for it so they 'value engineered' it out in '06 and beyond.

Thanks for clarifying! I just spent 20 minutes staring at my MC looking for that [bleed nipple].

Just like any car start with the furthest away from the mc, and go down.
