I have a track day soon and I need to flush my brakes on my 17 ZL1 and can't seem to find consistent info on which order the brake calipers get bled. On my 4th gen Trans Am it was always passenger rear, driver rear, passenger front, driver front. I've purchased the Motive power bleeder and plan to use it dry and only for pressure while keeping the reservoir topped off between corners, I have motul 600 fluid that I plan to use.

I've never had a car with inner and outer pistons on each corner either so can anyone who tracks their car and bleeds brakes often give me some tips?

This is going to be a shock. It kind of doesn't really matter what the order is. All 4 corners have their own line downstream of the ABS module. Whichever you pick first, that's the one that'll take the longest as you have to first push new fluid from the reservoir to the ABS module inlet.

For those that "must" do it from longest line to shortest, it's LR, RR, LF, RF.

For each caliper, it tends to make sense to do the outboard bleeder first as that's the larger fluid volume and it will also inherently bleed part of the inboard passages simultaneously.

Probably the most important advice in all of this, is to ensure you twist up a paper towel really tight to a point and get the extra fluid out of the bleeder once you're done. It holds more than you may think, and after your first track session it'll end up all over your calipers. Either that or you didn't tighten the bleeder enough; these stupid Brembo bleeders need more torque than every other brand/model caliper I've ever touched.

Remember reading this awhile ago.

1. Right rear - inner then outer
2. Left front - inner then outer
3. Left rear - inner then outer
4. Right front - inner then outer

I know most people are using a different sequence[/QUOTE]

Thanks for the info guys, I'm going to give it a shot this week.

furthest from the reservoir first learned it in school and still use the same method today.
