    74' Intermitant Brake Light

    The brake light comes on randomly and I can get it to go off by tapping the brake petal a few times. No signs of leakage, braking is normal and master cylinder fluid level appears about normal on both sides - however a little lower in the rear side than the front. I do not know the entire history of the brake system but I believe the wheels all have stainless steel sleeves and I know the brake hoses are new. I think the master cylinder is original and untouched.
    I am thinking my problem is the master cylinder and to pull it and have it sleeved and rebuilt. Any thoughts from others who may have had this type of problem?

    Based on your description, I'd have the Master Cyl rebuilt IMMEDIATELY before driving the car anywhere.

      The BRAKE light indicates a problem with the system. Based on your post, the cause could be the master cylinder. Regardless, check the entire system and ensure you have no obvious leaks.

        Is your pedal soft at all? I would bleed the brakes first thing.

          Bleed both rear calipers and see if you have results.
