ZL1 Brake Bleeding

nicktechla · 02-13-2018, 12:09 AM

There seems to be a lot of different procedures for bleeding order, but a few people said the GM service bulletin was RR, LF, LR, RF. Is this correct?

Also, Brembo is usually inner bleeder then outer bleeder I believe? Is that correct?

and nothing special for ABS, as long as I don't introduce air into the system right?

usually want to bleed furthest from brake reservoir which is front drivers side. Correct procedure would be RR, RL, FR, FL also would want to bleed outside Bleeder valves first then inside bleeder

Everything I've found on the internet about Camaro's is what you posted above (OP), including Inner and then outer. I've never personally seen the GM Service Manual though...

Should go

Right rear
Left rear
Right front
Left front

Then how ever the manual says for the inner/outer bleeders. Just remember to check the fluid in the reservoir after each wheel.

So I am trying to figure it out also. Normally you do furthest away from the brake reservoir but on these cars the ABS system is not on the same side but on the passengers side. So does that change things when bleeding?

I'm surprised to find this, but the service manual actually says to do RR, LF, LR, RF. Inboard then outboard bleed screws on the calipers.

I have personally done RR, LR, RF, LF when I switched over to DOT4 last year, and this year used a GM service tool that instructed me to do LR, LF, RF, RR. Didn't have an issue with either of the ones I did. There's really not a lot of backflow of fluid in the system when braking, so overall order doesn't matter as much.

I'm guessing that the service manual order is due to how the brake system is split. These cars most likely have diagonal split circuits instead of front/rear split, so if this is true then this order bleeds one circuit at a time.

Inboard/outboard order on the caliper is mainly to help with cross-contamination within the caliper. Is there really any huge benefit to doing inboard or outboard first? I'm guessing not so long as the system is bled thoroughly, but I figure I might as well follow the manual when I do it because it's not any harder to do one way vs. the other.
