Radio interference from front brake calipers (Peugeot 305)

1. On models prior to 1986, radio interference may occur from the front brake calipers (especially when driving on wet or salted roads). Interference passes to the radio receiver through the wires of the brake pad wear sensors.

2. Interference can be reduced by grounding the front strut calipers or piston rods. The latest DBA calipers have a special 5mm diameter hole in the anti-rotation plate for connecting the ground busbar. Girling calipers have a blind, tapered hole next to the brake hose connection that can accommodate a 5mm diameter, 0.8mm thread pitch, 10mm maximum length screw that serves the same purpose.

3. Do not drill holes in the calipers or attempt to modify them to remove interference. In difficult cases, you should consult a specialist.

4. On GTX models with DBA calipers, the ground bar must be secured with the mudguard mounting bolt.
