New to this forum, picked up a very nice Nepal Orange 1976 with under 50k original miles. When I push it backwards in the garage it rolls without resistance, however when pushing it forward I hear the calipers rubbing on the rotors and feel resistance. May need to just drive it more but need to get it registered first. PO did not drive it as it was in his collection with many other Porsches. Other than driving it more, any other possible causes? Seems odd it rolls fine backwards. Looking at service history, PO did have the rear brakes done at 47,421 miles in 2018 and only another 2500 miles since then. Replaced rear calipers, pads and rotors, flushed and bled entire system and adjusted caliper pistons and parking brake.

I would jack up the rear of the car and spin the wheels, then do the front. Get someone in the car to stand on the brake pedal and see if the wheels release nicely as soon as the pedal is released...if not, time for hoses and / or calipers. |

Thank you. |
