So today i replaced my front discs and brakes from brembo discs and pagid pads to Mtec discs and ebc yellow stuff pads.

Everything was cleaned properly, all torqued down to the recommended specs and copper ease grease applied to prevent vibrations.

now for some reason on the right hand side (drivers side) i am getting some weird grinding noises when braking, it only seems to be at 20mph or less( unless it is there i just cant hear it at higher speeds).

It was the same when i had the brembos and the pagid but was a lot less noisey.

Is it something to worry about? or do we think its the pads just bedding in?

The brakes work great and theres no vibration in the steering wheel when braking.

Can't quite get my head round that one.

You have gone from 2 of the top 10 braking parts manufacturers that there are to 2 of the bottom 10!
They were only standard cheap brembo discs and pagid pads. Wanted to upgrade to grooved discs for more visual purposes and ebc yellow stuff as I’ve hearf good things about the yellow stuff

Just finished restripping that side and re assembling couldn’t find any problems and the grinding is still there.

Even if yellow stuff isn’t the best is still an upgrade from what I was using as you can feel
The differnace.

I understand grooved and drilled disc may have less surface area on them for braking however I was going for more visual then anything as all
My research suggests there isn’t a massive difference in performance between what I
Got and standard vented atleast for fast road use.

Whilest we are on the topic also what makes a good brake disc? What is the differnace between a pair costing £120 and a pair costing £70? I know for that sort of price range your be looking at gray cast iron but does one have more graphite in it? Does one work to tighter tolerances or been heat treated better? Generally something that I’ve been thinking about the last couple weeks

Grooves discs are noisier than plain ones.
