i noticed something didnt feel right yesterday morning so i had a little experiment when i got home a little while ago. i reversed into my drive as normal and as there is a slight slope, expected the car to roll forward but it didnt. i reversed a little bit and dipped the clutch and the car stopped as though i had used the brake. there are other possible factors:
there is a plastic sounding rattle from under the car somewhere which i suspect may be the discs/pads
in winter i had no braking at all sometimes
brakes are good in the dry, not as good in usual wet weather (to be expected) but virtually non existant in very wet conditions
they did pass the MOT with all of these symptoms but this sticking is new. the front tyres are about to be replaced so i could use some ideas to throw at the fitter so he can have a look while the wheels are off anyway
