I am swapping out a 4.10 3rd member for a little more practical ratio & I want to upgrade to disc in the rear while I have it apart. On a manual brake 426 car what is the most effective conversion kit to slow this beast down?
Just thought the disc,s would be more effective with less pedal pressure, as it’s a no vacuum max wedge carAre you going to be racing the car on a course w lots of turns? If so, disc "can" help w brake fade. If not, then drums in the rear will stop you just as well as disc's in the rear. So unless your racing or doing it for looks, you can save money by leaving it drums in the rear.
The stock drum brakes are a self-energizing design.Just thought the disc,s would be more effective with less pedal pressure, as it’s a no vacuum max wedge car
Sort of, yes. The term self-locking might make more sense. More leg pressure is needed for disc's.Is self-energizing in that the shoe is designed to increase friction at steady pedal pressure?
Seems logical-----probably a lot more surface area in a 11" brake shoe than a 4" disc pad. Plus you have the leveraged pressure that the disc also does not have. I just know it has a lot more go than stop. ThanksSort of, yes. The term self-locking might make more sense. More leg pressure is needed for disc's.
The reason the shoes have less lining on the primary (front) shoe is to keep the front shoe from grabbing the drum too hard. The extra lining on the rear (secondary) shoe adds to the friction area without digging into the drum. As the drum turns and the brake is applied the front shoe rotates a little bit while pushing on the rear shoe thru the adjuster. The shoe assembly pivots on the anchor at the top center. Many earlier designs had a wheel cylinder for each shoe as well as a anchor for each shoe. These were not self energizing and took more effort to use. Engineering is a wonderful thing!Is self-energizing in that the shoe is designed to increase friction at steady pedal pressure?
Thanks Mike-----Engineering is a great thing, but we can't let it overwhelm our common senseThe reason the shoes have less lining on the primary (front) shoe is to keep the front shoe from grabbing the drum too hard.
