Brake Discs and Pads Front in Vantaa

When front brake discs need replacing

Brake discs wear more slowly than pads, but the disc thickness decreases with every pad change. The manufacturer sets a minimum thickness for each disc, normally 2–4 mm below the original figure. Below that point the disc no longer dissipates heat effectively and braking power drops, especially once the brakes are hot. Warped discs cause steering-wheel vibration during braking. The vibration comes from disc thickness variation, which develops when the disc distorts under heat — typically after a long downhill braking event or when hot brakes are suddenly cooled by water. New discs are always fitted together with new pads because used pads have already bedded in to the worn disc's surface and won't mate evenly with a new disc. This ensures maximum braking performance and a long service life.
