Hi, I have a 03 Passat 1.8T FWD. I recently did the brakes and after doing to brakes, they started to squeak, a lot. After that I took them off and clean the surfaces and add more lubrication than I did before(I didn't add enough before) to the guide/slider pins and the mounting surfaces for the pads. After that I drove again and brakes didn't squeak for a day and after that, it went back to squeaking about every other stops I did. The brakes don't squeak when I drive, sometimes when I turn I think I hear a squeak, but mainly when I brake. I am just in a rut about what could be causing the squeak on the brakes. Any help is appreciated. Thank you!
