Brake pedal issues
My 89' Corvette is starting to give me an issue with the brakes. Earlier this year I installed SS lines all around. Completely bleed the brakes and have always had a good pedal. Lately when I first apply the brakes backing out of the driveway the pedal will travel almost to the floor. I left off and immediately step on the brake pedal and I have a firm pedal. This has happened when I head up the street and go to stoip at traffic light pedal goes down if I leave off then immediately step on it I have a great hard pedal.. The pedal never travels to the floor and I have some brake action. When the brake is hard it does not move or slowly travel at all?
I have the same fluid in the master cylinder reservoirs. This has started to happen more frequently. I stopped in my drive and the pedal went down I left off then pressed down again and had full pedal but this time when the pedl went down the brake light came on? It went off when I released the pedal then stepped back on it.
Not sure if its ABS/Sensors or Master Cylinder issues. Any thoughts or help out there?
1989 Coupe L98 nothing special, auto trans.

I would wonder if the ABS system was bled out when the fluid emptied. That or the master cylinder might have issues.

to me that sounds like "volume" being filled successfully by the mc pumping the fluid.
either air, which would be the most common and obvious. or lines expanding, or a caliper piston sticking in the "out" position.

A tech 1/2 can cycle the system during a flush or bleed.. Its not hard for a dealer to do it.
Its trusting a dealership to do it.

They may be hesitant to work on older cars and either say they don't have the right scanner or quote an insane price Seen that before.
I do not trust them but I don't have the luxury of ignoring them. I read up on the procedure and WATCH CLOSELY when they work. Small compromise but a deal breaker if you don't agree
