The link above is the EXACT kit that I used. Leed Brakes (formally GPS) This kit will give you everything you need from the brake pedal to the brake rotors. I can't recommend this enough after driving the car. It feels absolutely amazing. Its safe, reliable, and perfect for your daily drivers or weekend cruisers. This is also the factory style brakes. When your brakes pads wear out, you can walk into any local auto parts store to get replacement pads. You don't have to special order them online and hope the manufacturer still makes them. I will provide a link for automatic transmission and manual transmission cars.

    I have a question, do you have to have the brake booster?

  • @AlfsMustangGarage

    @AlfsMustangGarage

    3 жыл бұрын

    No you don't. The booster is simply a vacuum chamber that assists you when you push on the pedal. Essentially makes it feel softer and more like a modern car. Without the booster, the pedal just feels stiff. Which is fine and you're probably used to it feeling stiff with an old car.

    When you go to install the control valve, it's crucial that it goes back in the same position. Make sure you mark it before you remove it. Also when you remove it, don't use a pickle fork like I did. It will just rip the ball stud out and then it will be stuck in the pitman arm.

    Thanks for the instructional videos... very helpful. I do have a question. In my 65, I added front disc brakes and left the rear drum as is. I can only fit a single bowl M/C ( shock towers are in the way for a dual bowl) along with the brake booster. What I have found is once the installation is complete and lines are all bled, it seems like braking is different. In doing a test drive....I am pushing the brake pedal more..seems like to the floor....more than when I just had drums all the way around. Is this common?

    Two things to look for if you can't get fluid to bleed out the rear. The rear brake hoses can swell shut from the inside. Also in the brake distribution block there should be a brake pressure warning switch. If there is a brake fluid leak, there is a shuttle valve inside that will shift towards the direction of the leak and block fluid flow off. This can inadvertently happen when bleeding if you don't use the special tool to prevent the valve from moving.

    So the pressure differential valve is simply that. If you loose pressure on the front system or the rear system, there is a shuttle valve that will slide in the direction that brake fluid is flowing through (or leaking) and ground the switch thus turning on the brake warning lamp. That indicates to the driver that there is a loss of brake fluid pressure. In no way does that proportion different pressures to front and rear. If your Mustang was factory equipped with front disc brakes, it came factory equipped with a proportioning valve that was separate from the distribution block. Cars that were factory equipped with 4 drum brakes, only received a distribution block. Look, its okay to learn something new so don't take it from me. Its not my business to sit here and try to convince you that you're wrong. Go do your own research and then you can come back on here and let me know what you find out.

    @@AlfsMustangGarage you’re 100% correct. Since the car was all drum, it was just a distribution block. Had it been a factory front disc and rear drum, for this year, it would’ve probably had an in-line proportioning valve near the rear axle. Don’t think they started with combination valves until some time in 68.
