My dad & I put his 67 GTX together w/ front drum brakes. He has passed away. The GTX pulls to the right when you put the brakes on hard. It has every thing new. I mean every thing. I bled the front brakes & its getting plenty of fluid. I had some one hold the brake pedal & I could not turn the left brake but I could turn the right side. The right side is where the car bolts to when putting the brakes on when driving it. I am confused. Any help Thanks

A pull to the right (& vice versa) means the left side ain't doing its job. spoon up the left side (wheel off the ground/spin it forward/spoon it till you barely hear a "tick" at one point in the tires' revolution, a tick that you "hear" but do not see/feel it slowing down the wheel revolution). & see what happens & if not satisfactory then open it up & see what you see.

Originally that car had manual adjust brakes, make sure they are evenly adjusted. Did you get any fluid on the shoes? The fluid will make them grab and pull.

Possibly a restricted hose or stuck wheel cylinder making the right side not hold. Take it apart and make sure it's not leaking.

Did you put a copper washer between the hose and wheel cylinder?

Don't rule out the rear brakes because they can cause a pull also.

make sure there are no ridges wore into the backing plates where the shoes ride. this can cause the shoes to not retract properly, allowing one side to contact the drum surface before the other, causing a pull.

Thanks guys. Even though dad put on new wheel cylinders about 1,000 miles ago I went & put on new ones. Bled them & got a good flow of fluid. It pulls to the right so I loosend up the right side & tightened up the left side. No diff. Here is what has me baffled. The car pulls to the right. So I had my nephew push down on the pedal & I tried to turn the left side NO GO I tried to turn the right side YES I could turn the right side. It has front drum w/ power brakes.

Make sure the strut bushings are good/tight where they locate into front of K member.

Did you change the rubber hose? Sometimes they cause the problem and they are cheap to replace.

Everything is tight & all lines rubber & steel are new.

Was the engine running when nephew pushed the pedal? No power assist when engine off.

Are they still manual adjusters? Did any fluid get on the shoes at either repair job?

How are the suspension bushings? Did it drive OK going down the road. A bad upper control arm bushing will make a pull when braking due to caster change.

No car wasn't running yes manual adjusters shoes are clean whole suspension is new drove straight as an arrow all of front brake system is new except for the backing plates & the brass fluid dist. block

With the front end up, brakes pedal applied, a person can turn the right front wheel but not the left front wheel. The odd part is while driving, the initial application the car steers right.

My guess is the distribution block connections are crossed. Is that possible?

Otherwise, start a step by step checking. Check the rears the same way with an assistant.
For each wheel that can be turned when the pedal is applied, does it resist slightly indicating some hydraulic action.

Bleed the problem brakes - does each push of the pedal move about the same flow as a working brake?

Goal here is to identify if its a hydaulic issue, and if so where, or a mechanical issue.
