Conversion powerbrakes C2
I'M upgrading the brakes on my 65 convertible to powebrakes. Have a kit from Ecklers and now I meet a problem. The rod and gabel witch connects the vakuumbarrel and the brakepedal is to short. The gabel are adjustabel on the rod but even if I adjust it so the threads only go throug the gabel halfways the brakepedal sits an inch under the level of the clutchpedal. I think I've read about it in the forum but can't find it. Anyone who has met this problem. Thinking of fabricate a new longer gabel.

some others who have done this will chime in but I think you need to change the brake pedal pin to the hole for power brakes on the brake pedal itself . . but I would call Ecklers and ask for advice.

Ecklers was the first issue, good luck calling them.
Post some pictures if you can. You could use a coupler to extend the rod if you have the clearance or find a longer rod.

I use the lower hole. When i have full threads in the clevis the brake pedal sits 40 mm below the clutch pedal. I can compromise and not have the rodthreads all thru the clevis and maybe gain 10 mm. It will althoug be a differenc 30 mm and it doesnt feels good not to use all thr threads.

Of my three Corvettes, the only one with power brakes is my ‘69 and the brake pedal sits about 40mm (little over an inch and a half) below the clutch pedal.

Thanks for that answer, I'll go on with the setup and try to accept the difference in hight. But when one problem is solved another appears. I bought a full set of new delco callipers, the boxes are marked Dr Vette and yesterday when I was going to mount them I found out that two of them had no threads in the mounting holes and the drilled holes has a larger diameter than the bolt so I cant just thread them. Also got a new blinker where te screws where so bad that I have to drill them out and thread the holes to a large screwdiameter. So bad that the qouality are so low on new parts. Specially for us living in Sweden, a return to USA and getting new products takes months and the cabriolet season are on its way.

I have a good friend who recently converted his 67 SB from manual to power brakes and went through the same thing. What you call a "gabel" we over here in the States call a "clevis rod end". Different names, same thing. My friend, who is a perfectionist, was highly irritated with the fact that the new power brake pedal sat so much lower than the clutch pedal.
There is a website that sells longer clevis rod ends. My friend bought a longer clevis rod end and installed it at the end of the PB threaded rod so thereby eliminated the inch of drop down below the level of the clutch pedal. He was able to fully thread the new clevis rod end all the way on the end of the threaded rod. It is solid and looks good now.
I have attached a link to the company that sells the various size clevis rod ends that you will need. Copy and paste the link into a browser and you should go right to the page you need. You can just order a longer clevis rod end (gabel) instead of having to make a longer one to take up the slack.
I am unfamiliar with any company called Dr Vette and I have long ago stopped doing business with Ecklers as a result of their poor customer service. Good Luck with it. C.J.

The premise of the lower pedal height is, one keeps the heel of the foot on the floor and swings the toe over to the brake pedal without applying too much force. Otherwise, if raising the foot to the clutch pedal height, you risk slamming into the brake pedal too hard. I believe all power brake cars, regardless of make, had similar pedal heights.

the problem with callipers is solved. They were labeled wrong, back ones in labeled box front and vise versa.
