NewbieWar

NewbieWar

anyone, this would save me some leg muscles that i dont really have

its usually right after i start my car but sometimes it'll be after i went about 5-6 miles its just i donno what its all about, im pressing as hard as i can my leg is getting tired and if i stop pushing the car lurches forward

all brake pads are new

LanceJoker

do you have a big cam in there or something?

Vacuume leak of some kind I'd guess. I think you can turn the car on, and spray carb cleaner (just a little) near your vacuume lines (especially your break booster) and see if the idle changes or stumbles. For the record I have never checked for leaks this way, just hear of someone else on this board doing it

You can also use a vacuum gauge on the brake booster line, check the the plastic fitting going into the booster.
