Breaking problems

[Poppe]

I went to the car inspection company (Bilprovningen) the other week and got a remark that the front breaks are not even enough. The difference was som 35% (30% is allowed).
I bought new breakpads and discs and made sure the calipers could move freely.
Getting back to the inspection, now the breaks are even more uneven but this time the left breaks more than the right. Before it was the opposite.
This unevenness can not be felt while breaking hard on a normal road. The car steers straight.

Anyone else got this problem ?
What to do ?

Maybe you forgot to clean discs before use. They are covered with wax, and this will give uneven breaking.

Actually I did clean them but maybee not enough.
I will take them down and re-clean.

After a second very thurough clean both side breaks where even and great. I must have been less energetic when cleaning the right side.
A little surprising though that the wax does not come of by itself when breaking.

Anyway, thanks for the tip elekrolux !
