Good morning! I need some help with my brakes. I bought my 1930 Brookville Roadster from its second owner. It has manual Wildwood 4 piston discs up front and drum brakes in the rear. No power.

Ever since I purchased the car, it seems the braking isn't what it supposed to be. I started driving in 1963, so I know you have to apply more foot pressure than with power brakes. The problem is they won't allow me to bring the car to a quick "emergency stop".

I had a mechanic friend drive the car and he agrees with me on the lack of stopping power. However, when he looked at the brakes, he found that the front pads and rear drums are fine.

The car is equipped with a Wildwood Adjustable Proportioning Valve (APV). I'm new to street rodding. Will adjusting this help and if so, what is the proper procedure for adjusting the valve? Is this something I can do or should I trust this to a professional?

Thank you in advance
