Hi guys, I’m having a problem with a 73 Cuda power front disc brakes pulling to the right.

This car was restored a while back and was braking correctly up until recently. It had new hard lines, rubber flex lines, and proportioning valve when restored and new master cly. and power booster about 4 years ago. Also has had new front suspension components, new steering box and an alignment. It has 17” wheels on the front and the front is lowered approx: 1.5 inches lower than stock on the stock torsion bars. The brakes worked well with this set up.

This problem started about 50 miles ago and I have since put on another new set of calipers, rotors, stainless flex lines and bled the brakes very well. I also noticed the brake pedal was not returning to its correct raised position, I put a new vacuum check valve on the power booster but it still stays down about 1 inch.

After I bled the brakes and took it for a test drive, I took the lid off the master cyl. I noticed small bubbles coming up from the hole in the bottom of the front brake reservoir. I check everywhere for leaks but could not find any brake fluid leaking anywhere.

Any help would be greatly appreciated.

Thanks
Doug
