When I am indicating left or right all is ok until I brake then the indicator light speeds up and the mileage light on the dashboard flashes bright and dull alternately. I have replaced the Brake/tail bulbs and it appeared corrected immediately afterwards but is now happening again.

You may have a bad earth on your rear lights.If your car has a towbar Check the wiring.The most common problem is the earth wire to the bulb holder. Get someone to look at the rear lights whilst pressing the brake with the indicator on you will probably see all the lights flashing.
