All brake discs warped

Find a different mechanic.

Ask old mechanic for recommendations if needed.

When your mechanic supplies parts , if there is a warranty issue , he should be standing over the parts, ie not charging labour to change them again..

They charge a premium on the parts so mske a profit on them.

When you supply parts , if there is an issue , they have no real responsibility warranty wise..

I will admit that it is getting harder and harder to find good reliable mechanics.

A share have closed or retired near me recently.

Whats left doesnt want the work, arent taking on anymore work ,arent reliable.

A friend supplies his own parts but says he has to check whether those parts get swapped out for cheaper parts. But still goes to that mechanic

I try and fit ATE brand brakes whenever possible, they can be expensive but they are good quality and last a long time.

Apec are absolute muck, I refuse to fit them.

Yeah Brembo stuff is good.

I often use Ferodo pads with various other brands of discs when people are trying to save a few quid.

I fit a lot of the ATE stuff and have never had an issue, try them out, you won't be disappointed, better value again from Autodoc.

It’s unlikely all four discs are truly warped; more often it’s surface rust, pad deposits, or the car sitting for a long time causing poor contact. Real heat warping on all corners is rare. Budget parts can be sourced from Autodoc if you’re keeping costs down.
