Clio brake pedal is shuddering

[Angelica67]

I have a clio, old W reg, and the brake fluid kept dropping, so I took it to garage, they had it all day and said it was the brake pipes, theyd leaked and started to erode something on the back brakes?? Anyway... paid loads to get it sorted and next day it was juddering on the brake pedal. Can anyone shed any light as to what this is and is it dangerous... and will it get better or do I have to take it back in?? Im needing to drive long distance tomorrow so desperate to get this sorted... please help...!?!

It sounds like one or more of your brake disc's are running out of true. if this is the fault then the bad disc/s will need to be replaced, but if you do need to change any always change the two example if you have one bad on the front always change both of them and the same if you have one bad disc on the rear.

Thanks tonyav. Well they said theyd changed the discs... the car seems ok but its the juddering on the pedal that bothers me, have no time to get it sorted either and need to know if its safe as Im taking passengers too... ooh.. dilemma!

Get them to recheck those discs could be one of the new ones is dodgy, or could be lose.

unlikely the disc is loose, once the wheel is bolted on it holds it in place, many manufactures dont use any bolts/screws to retain the disc they just fit over existing wheel studs/bolts.
Was it juddering under normal braking ? or hard braking ?...could be the ABS kicking in under hard braking

Hi, there are a few things that could cause this, as said, Disks, Brake Pads, Brake Fluid on the Pads, Caliper bolts/ Torx bolts loose, I think you mean Back Plates they are at the rear of the Disks, they should not have returned the car to you without checking the car, for your own & your passengers safety TAKE THE CAR BACK.

Sounds like your brake discs are uneven
