Hi there, I used to have an intermittent pulsation on my brake pedal when braking at low speed , I changed all my discs and pads but the problem got worse, the pulsation got worse and I started having some squeaky noise when braking, my mechanic suggested the cheap parts I bought online from euro car parts were the cause, at this point I decided to buy a better quality front discs and pads (in case the discs were warped) ,,,,unfortunately this didn't fix the problem either. I don't know if I should change the rear discs and pads as well or this is going to be money down the drain again
Can anyone advise please?
Could this be the abs /abs sensors/ or simply the rear discs.
As I said its a frequent pulsation on pedal at low speed (below 40m/h)

Any help would be appreciated.

Thanks

Hi Samir,welcome to the show
i would mind about that sqeaking sound,thats just some pads doing,mine is sqeaking too.
about that pulsation,dont know,you did change discs,pads,so that is not problem,perhaps brake fluid and pipes?

Welcome Samir!
When you fitted the new pads did they slide freely into the caliper or were they a tight fit?
On some pads they have "hrns" on the top that need filing down to allow the pads to slide freely; also make sure you give the calipers a damn good clean and smear some copper grease on the back of the pads.
Re the squeal; you can minimise this by filing a chamfer around the face edges of the pads.

look for abs ring in the search box , think you will find that one of
them has split .

Over the 7 years I`ve had my 406,i sometimes get the pulsating pedal at slow speed.Normally after a few days or a week or so the abs light will come on and the pulsating goes away.Its normally the abs ring on the cv joints or rear hubs,or a abs sensor.

Puggy has a sensible suggestion, take a look here....

Thank you all for your suggestions , I have just come back from Wales and the brakes were fine on high speed, still the same problem when driving slowly though, I am popping to my friends garage to check out the abs ring and sensors and I wil keep you updated.
