Question about 1993 Pontiac Grand Prix
The brake pedal touches the floor and still don't get brakes, how do I check to see if there is air in my brake line/s ?...
If the brake master cylinder reservoir is full of brake fluid, and you haven't had to add any recently, then you probably don't have any air in the lines but may have a bad master cylinder that isn't capable of building up fluid pressure. If you've had to add brake fluid recently because the system was low or empty then you may have both air in the system and a leak that is allowing brake fluid to escape. Possible spots it can leak are at brake hoses, brake lines, wheel cylinders, and brake calipers, just to name a few. Either way, don't attempt to drive a vehicle without good working brakes as it is very dangerous to do so. I would have a good shop check this one out and give the entire system a thorough checking over to find out what has gone wrong. Good luck, hope this helps a bit.
