1969 Mustang when braking car pulls to left?

Hi,
Over the past 14 years I've rebuilt this car from the ground up...entire new brake system too. It recently started to pull to left when braking. Tires are new and balanced. I don't drive the car very much maybe 15 miles a month in the warmer months only. The car has manual brakes with drums all around.

Any thoughts?

thank you

Lets start with a bleed job. Possibly right side wheel cylinder stuck. Or go ahead pull drums and get an eyeball at the shoes. Might jut be a simple adjustment required.

It sounds like you tightend one of the brakes on more than the other.

Did you replace the flex lines? Old, internally deteriorated hoses can cause uneven braking. Take a look at the shoes to see if you have uneven wear from one side of the car to the other.
