Volvo pulls slightly to the left while braking

Hello, have a V70-1 Bj.2000 engine B5244S2 245Tkm. Only when braking the car pulls slightly to the left and I have to steer back. On the brake level no serious difference from left and right was measured in the brake effect front and rear. Axjal and external joint steering were made on both sides last year incl. axle measurement. No problem afterwards. Cross handlebars, shock absorbers, bushings, stabistangs is still all original. I think it’s due to one of these things. But you don’t. But it’s also because of the habit. Where do you start best? It’s best not at the cheapest but at the most sensible. Does anyone know what can be the most meaningful? VG
