Disc Brakes vs. Drum Brakes Disc Brakes vs. Drum Brakes
Pros and cons of both brake systems
Following are typical pros & cons for both disc and drum brakes:

  • Pro - Less expensive since they're already stock on Broncos
  • Pro - Drums work better then discs as emergency brakes
  • Con - They stop poorly when wet and can get clogged with mud
  • Con - Stopping power can fade with repeated hard braking
  • Con - Larger tires

  • Pro - More consistant, straight line stopping power
  • Pro - Dissipate heat better to stay cooler
  • Pro - Less affected by water or mud
  • Pro - Easier to maintain and faster to replace pads then shoes
  • Con - More expensive to install (but maintenance costs should be less)

Most people will agree that discs are better than drums. However, stock drum brakes can be effective if they're in good working order and properly adjusted. Typically when people upgrade to disc brakes they're replacing worn out drums, so they see a vast improvement and are quick to credit their new disc brakes. Just keep in mind that when someone raves about their new disc setup some of it is due to simply having new parts.

I like 4 wheel disc but it ain't necessary.

Boosters are nice. Hydroboost is the best and cheapest.

I was part of a bronco club back when I was a teenager and FINALLY got a chance to get another one. I just picked up a 1975 Bronco and was wondering if some of you may know what ford parts will swap onto these broncos?
Parts such as Disc Brake swaps and power boosters. What other cars will the parts interchange from?

Proportioning valve issue. I have a 1973 uncut EB. Just finished restoration with conversion to discs front/drum rear with new MC and brake booster. However, I’m having an issue with front brake drag. The pistons are not releasing and I have burned through a set of brake pads. Calipers/pistons are not frozen. Any insights as to how to resolve this issue? Is there an adjustment that needs to be made to the valve?
