I replaced the drivers side wheel bearing Saturday when I left the garage the brakes felt tight mainly the pass. Front,the next day the pass front started to squeak when applied mainly a slow speeds or when coming to a stop. I looked everything over while still together all looked good pads still good no noticeable missing parts, Sunday night the wife went to drive it came back in and said it felt funny and she didn't want to drive it. I went out tried to back up and one or both front brakes were locked up, instead looking at them I rocked it forward and backwards till it popped and was free and was fine. Drove probably a 1/4 mi. Crawled under it and again every thing looked fine. Tues. I replaced the pass. Wheel bearing looked over the brakes nothing looked off, rotor looks perfect still had stiff brakes and loud squeal tonight I hit the brakes pedal went straight to the floor quick pump brakes were fine, next pedal hit was stiff pedal then slowly to the floor with no help from pumping and when I backed into the driveway had a very hard pedal with instant brakes. Would the hydro or master throw the abs light? The master is a little low but I didn't notice fluid any where
