Hey everyone, my name is Dan and I just picked up a 68 CDV. I have been into motorcycles for a while now and I have been wanting to get into cars as well. I LOVE the style of 65-68 Devilles and I found one locally for a decent price. She has some cancer but only 89,000mi on the original 472 and trans! All original trim/emblems/hubcaps, all power windows/seats/antenna/radio still work. I would post pics but it keeps telling me I dont have enough posts to post pics so I'll post them when I can. I do have questions though, I dont have a manual yet and I haven't had a whole lot of time to tear into it yet but the brake pedal is sticking, I have to pull it up with my foot. Would this be the MC? Or a wheel cylinder? Any help would be much appreciated!

I had the same problem with my '69. My solution (temporarily) was to take a big spring and hook it to the pedal to pull it back up. There was actually a hole in the pedal shaft to threat the spring through and everything.

Works great. Hope that helps and welcome to the boards.

Nice! I was thinking of hooking up a rope or wire and have my wife pull the pedal up as im driving! (she didnt like that idea) As soon as I get a chance I may try bleeding the brakes to make sure there are no air bubbles.

Oh, and if anyone has a line on a good manual, I need one. I found a CD on ebay, its a shop and body manual (I'd post a link but I still dont have enough posts yet) Does anyone have one of these? Are they any good?

Thanks

that or the factory service manual are usually good resources. and Ebay seems to be the top choice for finding them.

I have the CD-ROM for my '69 and it's good, though sometimes inconvenient in that I have to print out pages for reference when working on the car.

Congrats on your new '68! You'll love it!

My bet would be a problem with either the vacuum booster or master cylinder. If your wheel cylinder (s) were not returning, your Cad would not stop evenly and would pull to the side when you apply the brakes. Congrats on choosing a great year for Cadillac!

Yeah, I dont really notice it pulling to the side at all. Thanks! I am way stoked on it! I was thinking about lowering it just a tad and keeping the rest fairly stock looking, It does have some cancer at the bottom corners of the rear window (it was a vinyl top) that I will have to address, does anyone have any good resources on doing this kind of work? I am a pretty good welder, but I have never done auto body work. Oh and I guess I am able to post pics now :)

Looks a bit rough, but these are durable cars and I'm sure you'll have her whipped into shape in no time. Keep us posted on your progress!

Do you plan on redoing the vinyl top or no?

Looks like a pretty solid project. Only two spots that need metal.

By the way, do you know what color she is/was? If not, ask Bro-Ham. He's the resident color specialist. :)

If that green is original, it's #30-Silverpine

Welcome to the forums. For the brakes I would start by flushing the system. There are a few reason why your pedal might not be coming back up. You may be missing the pedal return spring (as mentioned above). Also, the seals in the master cylinder may have swollen causing excessive resistance. Is it hard to push down on the pedal? Brake fluid is hygroscopic, meaning it has an affinity for water. It is designed this way to keep moisture from damaging the seals or rusting out the brake lines from the inside. However, it can only absorb so much water. If the fluid is really old (I'm guessing it is) moisture may have entered the system and cause the seals in the master to swell.

Another possible cause is worn/binding return springs on the drum brakes. Remove the drums and shoes, get all the way down to the backing plate. Clean it off with a wire brush and then lube the landings where the brake shoes ride on the backing plate (there should be three easily distinguishable spots for each shoe). Put it all back together (remember to lube the star wheel as well) and then take it for a test drive.

I am sure that would look shiny new thanks to your works :)

Thanks for the replies, I cant decide if I want to redo the vinyl top, I dont think I will. It is/was green and Im pretty sure it was the original color, I think I might repaint it with the Silverpine, I kinda like it! Dirt Cheap, It doesn't feel very hard to push down the pedal. I haven't had time yet to bleed the system but as soon as I get a chance that will be the first thing I do. Thanks.

Stereo, power door locks, leather, and air conditioning! Looks like a good start to a well-optioned car!

Thanks! Ok here's the deal. This weekend I replaced the Master Cylinder and bled the system. The pedal still does not return. I did notice though that with the ignition off, the pedal does return. It feels like it should feel with the car off. But with the car running the pedal just stays at the floor. Im thinking vacuum booster?? Also, I couldnt see any return springs on the pedal itself.

Sounds like you're on the right track.

same thing as me. I'm guessing it's the vacuum booster on mine, too.

For now, putting a good sized spring on the pedal worked but come summer I'll be fixing the booster.

Yeah its gotta be the booster, I'll have to save my pennies and go pick up a new one. Thanks for all the help.
