1996 Chrysler Sebring brakes problems

Driving vehicle about 35MPH & started to apply brakes; heard loud popping noise; after leaving toll booth, another vehicle cut off sebring; hit brakes hard, heard popping sound; brakes didn't catch; went into spin & hit retainer wall, front end came up & smashed windshield; seat belt came unlatched upon impact; air bag did not deploy.

On the engine I had the pulley on the timing belt come apart and just last month I had the head gasket start to leak from the back. Timing belt 28,000 head gasket 37,500. I have had to replace all 4 tires that where on the car. All by 29,000 miles--some earlier and then later. The brakes were replaces at the same time as the timing belt pulley. I knew they needed replacement and had an appointment to get them replaced when the timeing belt went out. It is a 1996 but I only have 37,500 miles.
