Hello Skoda lovers

I have changed my disck brakes and put (Bosch) but after 3/4 weeks they started vibrate the steering wheel when i brake

Where can be the problem?

Here are a few pointers:

If you have changed the discs then I would check for rust or similar on the disc/hub mating surfaces.

I assume you have checked for loose wheel bolts?

I wouldn't drive until its checked thorouhly. Check the caliper retaining bolts plus if there the same as mine the calipers fit behind the carrier at bottom. I once had a garage fix brakes as front seized when away from home. They managed to unseize caliper but didn't have the bottom in the correct place. Caliper was loose and pads eventually slid out towards middle of disc. Wasn't happy at all.
