Brake Pad Problem

[De@nO]

I replaced my front brake discs and pads recently (DIY) with OEM stuff from the dealers.
Yesturday I noticed that my discs had started to develop radial grooves in them. On further inspection it seems that the pads have been 'chipping', causing these grooves I see on my discs.

Is there something wrong with these pads? What is causing this?

Thnx!

what pads are they brand ?

 

[De@nO]

Orginal BMW pads

and before u changed them did u go metal to metal? i hav never used oem bmw oem pads coz all they are ate pads with a bmw stamp i use farodo caramic pads they cost R480.00 inculding vat the ate/bmw pad used to last 10k the farodo caramic last 25k and i do about 2500 km per month

They were not worn down metal to metal.
I changed the discs at the same time, so it doesn't make a difference. (see first post)

How many kms have taken place since you changed pads and discs?

 

[De@nO]

About 800km's

hmm, looks like it got contaminted somehow... your supposed to clean the discs with petrol before you put them on... and bed them in properly
its quite possible that you got some bad pads dude :/ ...

next time just buy ATE pads from midas, its the EXACT same pad that BMW uses... so they are original. just doesn't have the bmw logo on it. nothing beats the stock pads... ferodo's are not as good as the stock pads, and ferodo's get REALLY noisy sometimes...

 

[shaunnorth]

mine are fine i have no probleams with ferodo's no noise nothing only thing i have noticed is the are much harder than ate and mt disk tend to suffer but R350 a pop @ midas not to bad

Thanks Clutch, starting to think they are also dud/bad pads :nono:
I used brake cleaner to make sure the discs were super clean before I put the pads in.
:thinking:

did you drive on dirt or a dusty road after rain or in rain

 

[De@nO]

hennie, I think just might have

 

[hennie]

that can cause this
you wont believe the amount of sand that lies on our roads and get picked up in the rain
on my rims i take about a tablespoon out of them after a trip of 300km in the rain
lightly sand the pad down with 100grit paper
if you can put the paper on a piece of glass even better rub it up and down till the shine is off the pads
these pads do look like they are hard as the disk looks like its already got a ridge
then try and avoid hard braking for the first 300km

the pads looks very hard, and the chips out looks like there were small pieces of metal that is missing.
