*How many times should you need to bleed new brakes?

On my Vette project, I had to replace the calipers. I think I have gone all of the way around the car twice now to get all of the air out.

Today it still feels like there's air on the lines. Is it normal for me to have to do a third bleed on an updated system?

A vacuum bleeder is about 30 bucks and is handy
Thanks, I will research that.
Whatever you buy can be used on any vehicle with hydraulic brakes in the future.

Check around local parts stores. Maybe one of them will rent / loan you a pressure bleeder for an afternoon.

It’ being a Corvette you are already paying double for everything else you buy for it. Ask me how I know 😊

Oh I know that one well! I remember learning early on that a regular GM part would be the same as a Vette part but they would give it a different part number to charge more :O

Unless you have a new master cylinder you need to replace that. Took me a gallon of fluid to figure that out on a C3 I had long ago after rebuilding the calipers. The seal gets trashed when you bottom it out in a rusty cylinder.
The booster's been replaced, but not sure about the MC. I've just ordered a pressure bleeder from Summit, and hope to give this a shot on Sunday.

Replace the master cylinder and save a bunch of time and fluid.
Pressure bleeder arrived today from Summit :)

What year is your Vette ??

Seriously, it's a '76.

Mine was a 76. What color exterior and interior? Mine was a low production color, Buckskin with a Buckskin interior.
In my opinion those flat glass C3's are the best looking of all the Vettes.

It's Classic White with Buckskin interior. It's pretty plain jane, but still gets alot of looks!

It could really use a paintjob, so I keep bouncing back and forth on keeping it original, or, just having fun. I also have a growing urge in me to pull the tired mill out of it and drop in a fresh 383. :)

Sounds like a nice one! I spun a rod bearing in my L-48 350 and ruined the crankshaft. Being I was needing a new crank anyways I bought a stroker kit along with some Wiesco pistons. I also put on some late 90’s Vortec heads and some Hooker full length headers and all that really, really woke that Vette up.
I have no doubt! Come over and help me do the same! LOL

I recently sold a C3 Vette that I had owned for close to 10 years and brake bleeding that car was far different than anything else I had owned. A power bleeder is your friend with a Vette and lifting the rear end of the car so the master is level was another great tip that I found out about.
So I have question on this: if I use the pressure bleeder that I just got, do I also need to level out the master cylinder as well?

it is helpful but not absolutely necessary. most helpful when disconnecting the pressure bleeder.
It worked best for me in an attempt to get the best pedal possible. There is a great article detailing this on the Corvette Forum. It is titled “Get the last bit of air out from the master cylinder”. I tried to copy the link for you on my smart phone but failed.
Tried the pressure bleeder and I failed. It started so well. Even with fluid in the jug, the rear reservoir still drained out completely. The pump also broke at 12 psi.

I tried to reach out to a "Corvette specialist" that I saw an ad for online, but they don't do house calls and are too far away. I don't know why this car needs to be so challenging.
