Scooby_Tez Posted June 24, 2023 Share Posted June 24, 2023 Hi everyone, New to the forum as I really need some help. I have a 2004 Impreza WRX Wagon. When applying pressure to the foot brake pedal there is a pulsing/grinding sound and feeling, the harder the pedal is pressed the louder and worse it gets. Usual things to check first would be the discs(rotors) & pads, however, car has just had new driveshafts; suspension struts; anti-roll bushes; discs & pads. Several months ago had lower ball joints; drop links & tie rod ends. No scoring on discs/pads when removed Only things now not replaced on front end is the control arm bushes, but, before and after these parts fitted the problem exists. Could it be something to do with ABS system? Just seems strange when it's applying pressure to the pedal like it's to do with the calliper, but as I say, new parts fitted. Any help or advise greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Linx Posted June 26, 2023 Share Posted June 26, 2023 Could it just be the heatshield touching the disc when you brake hard? Quote Link to comment Share on other sites More sharing options...
Scooby_Tez Posted June 26, 2023 Author Share Posted June 26, 2023 Thanks for the reply. I don't think it could be, they were checked to have clearance when new brakes were fitted and it happens when braking lightly not just hard. Quote Link to comment Share on other sites More sharing options...
