1999 Lexus RX 300

I own the car for 7 year and never had a problem with braking. It was always prices. I see the red light or stop sign, I push the pedal depending on the speed and it always stopped where I knew it will stop.

Lately, I noticed that with the same pressure on the pedal it stops bout 10 feet earlier. Then I have to release pedal and push it again to make to the stop line. Besides, even on the low speed the car kind of pushes back heavily. In other word, even I try to brake as soft as possible I'm getting a heavy push back which was never the case before.

I don't want to waste your time. I went to my mechanic who served my car all those years. Of course, the first thing he recommended to replace rear pads and rotors since they did have grooves. I did, but nothing changed even with brand new ones. He also checked calipers and said they work.

Any suggestions?
