brake bleed procedure for 2011 SS Camaro (and others)

[W.E.G.]

I searched around, and I didn't see a thread that exactly addressed this.

So, here's my take on it:

Note that Brembo calipers have two bleed-nipples (one inner and one outer) per wheel.

These questions came up:
• What caliper do you start with?
o Answer: Right rear


• What order do you follow from one caliper to the next?
o Answer: Crazy criss-cross pattern
 Right rear
 Left Front
 Left Rear
 Right front


• Which bleeder nipple do you open first?
o Answer: Always bleed the inner nipple first.


Per my research:

When bleeding Brembo two-bleeder calipers, be aware that there is a "crossover" passage that allows fluid to travel from the inner portion of the caliper to the outer portion.

The rationale for bleeding the INNER valve first is to prevent any upstream debris from being forced downstream into the crossover passage.

The four-volume Helm manual for my 2011 SS Camaro (with factory Brembo brakes) specifies that the four-corner SEQUENCE for bleeding brakes is as follows:
1. Right rear
2. Left front
3. Left rear
4. Right front

This criss-cross sequence is per page 5-173 of the Helm manual for the 2011 Camaro SS.

This criss-cross bleeding pattern is not at all intuitive to me. I'm just reporting what the factory manual specifies.

This same criss-cross caliper sequence, and also the inboard-then-outboard bleeder valve sequence, applies whether the job is done MANUALLY or by PRESSURE-BLEEDING.

If you have any doubts about what the manual specifies, or if you think I've confused the content in my report see it for yourself in the 5-page file on Google Drive at https://drive.google.com/open?id=1oT...R79Pc3ZCmUV1HP

With regard to the idea of upgrading to six-piston calipers, I don't know why any of this sequence would change just because you might switch from a four-piston Brembo caliper to a six-piston Brembo caliper.

Tank you very much for the information and all the tecnical brochure.

Would you mind to share the brake rotors procedure (Tork specs).

Thanks for posting!

I went though that some time back - I use my Tech II to do the bleed for ABS too:

I’ve got vacuum and pressure tools inbound for getting things ready for hard-braking season.

Unless someone beats me to it, I will try to get the requested torque numbers posted tomorrow as time permits.

Per your request.

Good information thanks, I am about to bleed my brakes again after installing a line lock. I did not know about the inner bleeders on each caliper.

I actually just read your post more closely.

My mind narrowly-focused on the hydraulic system, so I posted the torque specs for the hydraulic fittings.

I think maybe you asking for the torque specs for the installation of the rotor T-30 Torx screw, or perhaps the specs for the caliper-to-knuckle?

The spec for the Torx screw is 10 NM / 89 inch/lb

The spec for the FRONT caliper bracket is 60 NM / 44 foot/lb PLUS 90 DEGREES.

The spec for the rear caliper bracket is 40 NM / 30 foot/lb PLUS 90 DEGREES.

The spec for the caliper guide pins is 27 NM / 20 foot/lb .

Dear WEG

Despite my language barrier, you figured out my needs.

Definitly was the bracket specs.

Tank's again.
