Recently I had a new SSBC disc brake conversion kit installed along with a new power booster and dual M/C. Afterwards, I noticed that my brake pedal is much higher than the gas pedal (about 4-5") and seems strange this way. Is it possible to adjust the height? If so, what do I need? Thanks!

Were all the parts you installed part of the SSDB kit? Did you purchase your power booster or any other non stock parts currently installed in your brake system from a 3rd party other than SSDB? Most problems i read about are caused from mismatched brake components. If that is not the case you can get a shorter pin (rod) that connects to your brake pedel and actuates the master cylender.

Im not the expert. Id wait for the morning crowd for better answers than mine.

Your answer is the correct one. The length of the push rod is what determines the pedal height. There's no other adjustments to be made.

Mine is the same. I have a 67 GT with front disc. Can you buy the push rods individually?

I'd Check with SSBC. There are power boosters with adjustable push rods out there (you might even be able to change out the pushrod you have. Do you know for a fact that yours is not adjustable?

No offense, but the person installing the kit might not know, or realize that it could be adjustable.

Hello Earl:

I had the EXACT same situation this past summer when I installed
a SSBC front disk brake kit on my '66. All the parts were from the SSBC kit and the pedal was way TOO high. The SSBC supplied pushrod was too LONG and they don't sell shorter pushrods. Pedal height is determined by how far the pushrod (female thread) is threaded onto the rod (protruding through the firewall) which is part of the booster. Even with the pushrod threaded as far as possible onto the booster rod, the pedal was still too high. SSBC suggested that I cut a small amount off the male threaded rod on the booster. I didn't want to remove the booster & MC from the car (brake system was operational), so I cut about 1/4 inch off the booster rod from under the dash! That was tough. Because of the geometry of the brake pedal linkage, that 1/4 inch reduction in the length of the booster rod dropped the pedal to a normal height. You don't want to cut too much off
the rod & lower the pedal too much. You need enough pedal 'travel' to apply the pads & shoes and stop the car in a panic situation without the brake pedal arm hitting the carpet! Sorry for the lengthy post but unless you've gone through this, it's tough to visualize.

Good Luck,

Paul

PS: I did try a shorter push rod (designed for manual brakes) which is sold by Virginia Classic Mustang, but it was TOO short and I didn't have enough pedal travel before hitting the floor.

Paul and others, thanks for the replys. The tech support at SSBC were surprised by my call. The guy there claimed to have never had that complaint. He routed me to an engineer's voice mail. Paul, since I didn't install it myself I'll have to take a look at the push rod from under the dash to see what you are talking about. Is the suggested reduction 1/4" exact? Some mentioned a changing out the push rod for a shorter one, how is this done and who offers these? Any more suggestions would be appreciated. Pictures are more than nice!......

Id slowly trim it down. Trim it. Test it. Trim it. Test it. Because you can take material off but cant add it back on. I have no knowledge about aftermarket brake pushrods. Sorry.

Hello Earl:
I got caught up with home & work stuff but wanted to get back to you...
Other than the shorter pushrod which I bought from Virginia Classic Mustang (which was too short), I don't know if pushrods of other lengths are available. If SSBC doesn't know, then I doubt that they are available. The VCM pushrod was only 1" shorter, but it dropped the pedal below the
accelerator pedal level when the brake pedal was at it's up position (due to pedal/pushrod geometry)! From my experience, removing the pushrod requires removal of the brake pedal from it's pivot support. It's tight under there and one needs three hands. It's worth the effort because the result is a properly positioned brake pedal. I used a new fine
tooth hacksaw blade (without the hacksaw) to due the job. Thread the lock nut on the booster rod before cutting the rod so it's removal will clean up the threads. I will send you two close-up pictures of the pushrod linkage.

Hey, I know this is an old post - But my Brake pedal is way high - keep getting my foot caught on it as i move from the accelerator pedal to the brake. I'd love to see those before and after pics. I totally get the concept and my car is empty of interior upholstery, so now is the time.

Warm Regards
Todd

Do you have power or manual brakes?

With Manual Brakes it is easy to adjust the pedal height using a store bought or home made adjustable length push rod. I don't know about Power Brakes. Call or Email Dennis at CSRP and ask him.
