on the accord i picked up, the brakes are sketchy. there is no pressure to then, they go all the way to the floor. also, the idle is rough, but when i pump the brakes repetedly it idles just like it should, and the brakes work a little better for a few seconds. whats causing this? bad vacume line? any advice would help. thanks.
brake booster??, maybe the valve between the booster and the manifold??
check fluid level and for a fluid leak… but my money is on a vac line or leaking booster
i would hope that he checked the fluid level before posting here
