Default "Another" brake bleeding question (!)

As I write this, Mike Golding (a.k.a. Corvette Pilot on the forum, www.thepowdercoater.com on the web), is packing for shipment to me my newly-powder coated calipers.

When they arrive, I will do the caliper installation as well as replace the OEM brake lines with braided stainless steel lines from Doug Rippie Motorsports.

So, here's my question (finally!):

I would much prefer to lift only one end of the car at a time. So, can I do the caliper/brake line install on one end of the car and bleed that end while it's off the ground with the wheels off, and then move to the other end?

Thanks,

Rob

Go ahead and do it that way.

I usually have the entire car up with all 4 wheels off, but I usually just bleed the RR, LR, RF, LF.

I know what you're concerned about - the Service Manual says to do the RR, LF, then the LR, RF. I think that's more important if you're using a Tech 2 during the process to open ABS valves and bleed that part of the system.

Take a look at your master cylinder and you'll see a baffle in the middle - that's what separates the fluid so it either goes into the RR-LF circuit or the LR-RF circuit. There are 2 circuits for safety - if a line breaks or you otherwise lose pressure in the LR-RF circuit, the other one should still work so you can stop the car safely with the brakes on the RR-LF.

They are two separate circuits, so I can't see how they know what sequence you're bleeding them in.

So.....I would say that you can safely raise the car and do the rears and put the wheels back on, then raise the front and do the fronts.

Good luck!!!

Bob

The correct sequence for manual bleeding is:
  1. Right Rear
  2. Left Front
  3. Left Rear
  4. Right Front

Just make sure you don't get some of the calipers mounted upside down as has happened to some forum members.

Default Stainless Steel Brake Lines

I replaced my C5 OEM brake lines with stainless steel. I had never had any traction control codes before. After the brake line change I had random wheel sensor codes frequently. They were all historical by the time I made it to the dealer. I caught one active and he replaced a sensor after a lot of hassle. I can't say for sure that the brake line change caused the codes but it was a real coincidence.

Yikes, Mike... that's scary!

As you suggest, I am finding it hard to believe that there is a correlation between the failed sensor and the ss brake lines… but it is another thing to “think about!” Thanks for the heads up.

Thanks, guys... I am aware of the "school rule" regarding the 'proper sequence.' I am really asking about possible downside effects of doing it 'a bit' differently.

Like BEZ said, You won't have any problems bleeding right rear, left rear, right front, left front. I do it all the time.


And,
My wife was able to resupply our shipping supplies while I was in training today and get yours, plus the other 7 sets I did this weekend all out today!
