recently fitted grooved discs and red stuff pads,they seem quite noisy when slowing does it matter which way the grooves on the disc point ie.from hub with groove angled to rear of car or from hub angled to the front when viewed at top of disc

 

As I understand it grooved discs are sided, check the website to see if it has fitting instructions.

 

i thought so but no info supplied with the new discs and tried searching but still no good

cheers for the advice mate

 

Pretty sure that the grooves should point towards the REAR of the car, when viewed from the side, looking at the top of the disc:

cheers mate they are fitted correctly then must be pads just need to bed in

 

Grooved discs are known to squeal. Took my squealing grooved discs off and put solid ones one, no noise.

 

I've got grooved and drilled front, and grooved at the back and neither have ever squealed.

If you brake with the front window open, you can just about hear the grooves, they make a sort of buzzing sound, very low and low-pitched.

it is not a squeel on them it starts off like a low humming noise and then gets very loud like a drumming noise
i think it might be the rough layer on the red stuff pads that are for cleaning up old discs see how it goes with a few more miles on them
