Clunking Sound After New Brake Pads

[DieselPowerRules]

Hi everyone,

Just changed my rear pads today with Mintex ones. First 30 mins they were fine. Then I noticed a clunking noise on uneven road surfaces. Its more noticeable at low speeds (under 40mph) If I go over a drain or a bump in the road there is a clunk coming from the back. High speed is fine. Everything appears to be tight. I used the original backing plate from the old pads and put grease on to reduce brake noise. When I pump the peddle stationary there is no sound. Its only when moving. Any ideas? Thanks in advance.

I have the same problem. I used brake cleaner and the noise stopped for about 2 weeks. Then started again. I went to a garage, but cannot find anything wrong or loose.

It could be the pad backing plates are a fraction too small and moving in the caliper,Vx sell a 'cheaper' pad as part of a pad and disc trade set and they did this.
