Hi All. I bought car with what I thought was general ware and tear problems. Braking is fine until you get to about 5mph then there is Metal on metal sound & the brake pedal pulses. The metal noise sounds like it is coming from the front near the brake pedal, but nothing is felt in the steering so the problem I thought must be at the rear. Anyways I replaced front brakes & disc and rear pads & drums. Now the car slows fine then at about 5mph the same noise, but now is stops making a noise in the last seconds before the car stops, so there has been a slight improvement. Wheels spin straight and true. Any one any ideas what may need replacing or fixing or adjusting??? MOST GREATFULL.
