I finally traced down and repaired a nagging issue on our 1978 MGB.
It would drift right on braking. I had rebuilt the entire brake system when
I put it back on the road a couple of years ago (rebuilt/replaced: MC,
calipers, brake cylinders, all flex hoses). I replaced the A-arm's rubber
bushes. I tightened all suspension bolts front & rear. I rotated tires. I
had the front end (toe) aligned. Still drifted right on braking. It wasn't
really a pull on braking but it still didn't seem right. I re-bled the front
brakes and even measured that the volume of brake fluid pumped out from each
side was equal with each pedal stroke. I had the rotors turned and replaced
the pads. No change.
One day I pushed the MG back into the garage after we replaced the starter
on my son's pick-up. As the MG bumped up against a 4x6 block of wood I had
placed on the floor I heard & felt a 'clunk'. Something I probably wouldn't
have heard if I had driven the MG into the garage.
Turns out the rubber pads between the cross member and 'frame rails' were
shot. Although I had tightened the attachment bolts, I was only tightening
them against the stepped portion of the bolts - and not actually tightening
the cross member. I replaced the deteriorated rubber pads with urethane
pads. (the right side was essentially gone, there were remnants on the left
side)
Now she tracks and stops straight and true.
