I have kinda low vacume do the disc take as much vacume to work as the drum?
Low vacuum is no good for any power brakes .Would someone pm me my answer Do the disc take as much vacume as the drum to operate? Thanks
a power brake booster needs 16hg to operate correctly. put a gauge on it and see what your engine is pulling. they should still work halfway decent a tad under around 12-13.
I'm going manual for that very reason, I pull around 13Hg and it just isn't quite enough.
I have a comp cam pump I was gonna retire, So should I use it keep power and go to disc or just use the power drum brakes.
How hard do you drive the car? I see you are up in the valleys and mountains up there in Central PA....in that case, the disc brakes would be a significant advantage to you. They can take more heating on hilly/mountain roads and still brake well; drums will heat faster and lose stopping power under hard use. If it was me, it's a no brainer in that territory to switch to the manual discs, and ditch the vacuum issues.I have a comp cam pump I was gonna retire, So should I use it keep power and go to disc or just use the power drum brakes.
Power brakes on an a body are completely unneeded.
