Keep in mind that you will also need to replace your master cylinder and get rid of your factory combination valve. Both of them are designed for drum brakes, which require completely different hydraulic system properties.

As far as the combination valve goes, it has whats called a residual pressure valve that holds something like 6-8 psi on the rear drums to stop the springs from pulling the brakes too far back when you let of the pedal. If you were to keep that valve in the system with disc brakes, you'll be changing pads faster than your oil! But, that combination valve also has the proportioning valve in it, so you'll need to replace the proportioning valve. The best thing to do is get an adjustable proportioning valve to set the system up right.

The master cylinder is not as important as losing that combination valve, but on some cars and trucks, the residual pressure valve is in the master cylinder, so why chance it! Also, the resevoir is smaller for drum brakes that for disc brakes, and as the pads wear on disc brakes, the system needs more and more fluid to compensate. Honestly, it would probably never cause you a problem, but if you're going to spend the time and money, you may as well do it right!!

 

Amen..

 

Well called some junk yards where I stay and none have a 3rd gen Ram I can rip apart.My parents say they will get the conversion kit for me $900 isn't too bad for better stopping power.

 

your parents are too generous.

 

Front brakes do 70% of the stopping...... I could find a LOT of other things to better spend 900 dollars on.

 

you will also need the booster and master cylinder for the engine compartment as well. Not as simple as you think.

I would never do this swap, because you do not want your brakes to fail.

 

What exactly negotiates the reason you need rear disc brakes?

 

It honestly is just preference for me.I want a better look for the rear and don't like the bulky drum.

 

Not to mention, disc brakes are MUCH easier to work on....

 

So is that worth $900+? Crazy I tell ya'!
