[83_Silberpfeil]

For my 83 SC, I am experiencing the car pulling to the right when applying the brakes.

This is after I refreshed the brake system over the past few months.

- new pads, rotors
- calipers restored by Eric @ PMB
- new hard lines (attached to caliper)
- new rubber lines
- new fluid, bled out air

Two observations:

1) it seems to be more severe once the car is warmed up after a few miles of driving.
2) From visual inspection of the rotors/discs, only the front right/passenger disc showing circular marks. The other three rotors look barely touched by the pads.

It seems only front right caliper and pads are applying grip on the rotor.

After the brake project, with wheels mounted, and car still on stands, I rotated each wheel by hand/arm and applied brakes (by helper). Everything worked as expected, all 4 corners.

Where to start on this diagnosis - calipers/pistons, brake lines, MC, booster, vaccum?

Thanks!
