"My sedan has an aftermarket booster and master cylinder. The brake pedal is rock hard as in there is no swish in the pedal before there is braking, or another way to say it is there is no  pedal drop before I have brakes being applied. "

"I’m puzzled by your reply 🤔.  You stated aftermarket will be rock hard and same time one on your sedan and works great???"

"If the booster is an aftermarket one, they are rock hard on the pedal. I have one in my sedan and the brakes are great.  A vac pump is not necessary unless the vacuum is low. if the vac is low, then there are engine problems, not brake…"

Brake Booster not enough compression

I bought my 63 2-door convertible 62 series a few years back, previous owner said a new brake booster was just installed and that was why brake pedal was a rock.  Did not know.Just had engine reworked and I completely redid brakes.  Engine back in and running, brakes still like rock.  Mechanic only getting about 12-15psi I beleive he said.  He is not sure what to do other than add electric booster pump, going to test booster in morningAny suggestions before summer ends in OhioSee More

Finally got around to cleaning and re-lubricating the seat transmission. Now, it works flawlessly

Started by Norman Silverman in 1963/64 Cadillac Specific Discussion. Last reply by Russ Austin Dec 23, 2025. 2 Replies

When I first got my 64 SDV about 8 years ago, the power seat made noise but didn't go anywhere. I promptly read up on it and proceeded to take the seat transmission out to clean and re-lubricate it.…Continue

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
