Brake Issues

[Nikey30]

Hi All

I am seeking some advice on a current issue I have with my front AP BBK. I have recently swapped from AP discs to Performance Friction due to a vibration/pulsing on the AP discs which led me to believe I had warped them - even though I have never tracked my car. Anyway I have had the PF Discs on for approx 1500 miles (road miles only) and in the last few weeks the pulsing/vibration has returned and when driving yesterday the vibration was that bad that when braking lightly at lowish speeds I could here a slight knocking, obviously something isnt right.

So I pulled one of the front wheels off last night and have taken some pics of one of the discs and I also removed the one of the pads to see what could be causing this problem. I am running Pagid RS14 pads and these are the same set that I ran on the previous AP discs.

Should I have put new pads on when I put the new discs on the car?

From my investigation via the internet I think I may have pad deposits on the discs and the pads are potentially glazed. Can anyone take a look the pics and confirm if I am correct? I am no expert but would think the discs should have a cleaner/shinier look?

If this is the case then obviously a new set of pads are needed, I know that an agressive pad can clean discs up and remove deposits, so I assume the Pagid RS29 would be a potential option? Or do I need to get the discs removed and cleaned up at an engineering shop prior to the install and bed in of the new pads?

I would really like to get this resolved as I feel I am going round in circles with the brakes on my car.

Any guidance appreciated as I dont want to use the car at present due to the vibration as concerned its going to cause other issues within the steering/bearings etc.


Thanks
Nick
