I just put a new caliper with new pads and brake hose on the driver side of my 1972 corvette, when I tried to bleed the brakes I could,nt
get any pedal and nothing came out of the bleeder valve. I would appreciate any thoughts;
Thanks, Jerry

 

Do a search for Motive Power Bleeder here. I have one and swear by it, and so do many others here. I've never had better brakes than after using the power bleeder.

 

While I agree with C3, a little more information would also help. What prompted you to change the caliper in the first place?

 

right front caliper was leaking(car pulled to the right when brake applied)

 

Sorry, it was the left front caliper leaking

 

Do you have a part number for the Motive Power Bleeder, Thanks

 

The reason that I asked was that though the Motive bleeder is the quickest and easiest way to bleed brakes, it isn't the only way. You should be able to do the tried and true pump method and get it done.

Did you make sure that there was plenty of fluid in the master cylinder?

Did you have your assistant close the bleeder screw before you let off after each pump of the pedal?

Remember too that it takes a fair bit of fluid to fill an empty caliper.

 

yes, I filled the master cylinder, my wife pumped the pedal, but it went to the floor. We tried this method 4 or 5 times, but no resistance

 

You won't get much resistance as long as the bleeder is open. If you mean that you pumped the pedal 4 or 5 times, then it wasn't nearly enough. Try another 25 pumps and let us know if there still isn't any fluid coming out

Also, if the pedal is going to the floor, your rear brakes probably need bleeding too.

 

lol. I like the trash bag cover! I'll have to try that next time.

 

Thanks for the info, I'll try again tomorrow

 

Thanks for the info. I'll let you know how it turns out

 

I use a mighty Vac vacuum pump with the bleeder cup. this makes it easy.
I fill the Master cyl and then put the vacuum hose that comes out of the bleeder cup to the end of the bleeder valve and then open the valve. pump the vacuum pump over and over and then the fluid will eventually start to be pulled from the master to the caliper. After you have done this, close the valve, remove the hose and have someone do the old pump 3 times and hold it. At that time, open the valve and have a rag over the end and when you have good pressure or you don't hear any more air coming out (a spitter and sputter sound) then tighten the bleeder valve and be done. Some calipers have more then 1 bleeder valve on it so make sure you do this to every valve.

A few things to make note of...
Make sure you look at the fluid level in the master Cyl while doing this because if you run it dry, you get to do this all over again.
Start bleeding the caliper that is the furthest away from the master. IE the Passenger rear first, driver rear second, passenger front 3rd and so on.

**Very important** Have 2 rags there, one that is wet with water and a dry one. If you accidentally get any brake fluid on your paint job, STOP...DROP...AND WIPE!!! It only takes a short time to make some arts and crafts to a paint job with some brake fluid.

Here is a link to the Mighty Vac website and a picture of what I'm talking about. These are sold in almost any auto parts shops.

Good Luck

 

Just to let you know I pumped the brake pedal a bunch of times and finally got some pedal, I then bled them the old fashion way and now I have really good brakes. Thanks for the help. I appreciate it very much.

Buy motiva part #715-1105 from jegs. Get sprayer from wal-mart. Drill
hole in sprayer and put air pressure gauge. Fill up reservor, attach
cover and pump about 10 lbs pressure. Bleed the brakes. Check fluid
level after bleeding.

 

Well done!

Don't be too surprised to find a little sponginess after driving it. Not sure if bubbles get dislodged or just moved around but if you do have to bleed it again, a couple of pumps per corner should do the job.
