Brakes stop very slow
So I went to help guy with his brakes on 80 Jeep truck. The problem is that it takes forever to slow down the truck. All the pads/shoes are good (front pads were replaced), we bled system and pedal is firm. However if you try to stop it just won't stop, takes long time for it to stop.
Is master cylinder bad? I unhooked vacuum line to booster (it has power booster) and it has suction.
