Re: Weird Brake Bleed Order (Dreamin)
The Helm manual for my 99 Grand Prix GTP has it in the same order. I haven't looked up the bleeding order in my 2002 vette Helm Manual, but I assume it's the same? Doesn't make sense though...I would figure it's rear then front. :confused:

Re: Weird Brake Bleed Order (likev)
I've owned cars that the manual said to bleed fronts first and I can tell you it didn't work to do it differently. Don't ask...
Sometimes the engineers really do know something we don't. Or... maybe a misprint in this case, but I've never seen any mention of it. :rolleyes:

Re: Weird Brake Bleed Order (Avanti)
From the 1997-2000 GM Service Manual:
If it is necessary to bleed all of the brake calipers, the following sequence should be used:
Right rear
Left rear
Right front
Left front
But the 2001-2002 Manuals say RR, LF, LR, RF.
I would follow the Service Manual :smash:

Re: Weird Brake Bleed Order (Flyin'Brian)
In another post, someone stated that since 1986 GM has changed the Bleed order from model to model... so I dont think it's a typo in the '01 and '02 manual... i am just wondering WHY it's that weird order.

Re: Weird Brake Bleed Order (Dreamin)
The only thing I can think of is that they want you to bleed the system in halves. Modern brake systems are set up in halves, with each half doing a front caliper and the opposite side rear, that way if one corner is damaged and can't build fluid pressure, the other half of the system can still work. I don't see why they'd think it was important though, to flush each half in sequence.

Re: Weird Brake Bleed Order (Sam Lin)
VW made a big fuss about the safety advantages of having diagonal split braking systems in the 70's. I guess the Corvette has the same design.
