Why is my breaks light on after changing the master cylander?

I have a 1998 Honda accord. I got the brakes, rotors, and calipers changed. The brakes still locked up super bad. So we had the master cylander replaced. But now after driving it around the block the brake light keeps coming on and brakes are making a word noise when stopping fast.

Breaks, funny! | Your issue may be a sticking caliper of possibly something similar.

Sounds like you need new hoses and proper bleeding.

Bleed all air from the system. Start at the Right Rear, then LR, then RF, and end at the LF.
