Weird Brake Pedal Fault???

Hi

My Mk1 Octy TDi seems to have developed an occasion fault with the brake pedal. When, after braking you let your foot of the pedal and it returns to its normal position, you can 'feel' a slight resistance with your foot as though the pedal is sticking or snagging slightly on its return. Pedal always returns to its original position.

It does not do it every time you brake but I have noticed it getting worse.... I am a bit worried as we go on holiday on Saturday and I don't want it to let me down!!:confused:

Anybody else experienced this strange phenomenon???
