    Has anyone upgraded their brakes to all four disc brakes? Im about to get new rotorsfor the front, so I was thinking maybe all four wheels could have a nice rotor and brake caliper set up. Any ideas or has anyone even tried this?:confused: Would this even work?

    I'm sure the added(only) benefit is to be able to paint the caliper a bright color so it shows through spoked wheels.

    First language french? Disk should be spelled with a "k".

    The answer is that it can be done, in theory. There are issues related to proportioning though, and even more significant issues related to the emergency brakes.

    The big question that you need to ask yourself, is WHY? There is actually nothing to gain from this.

    Braking with 4 wheel disc would actually be better. Many truck manufacturers go to drum in the rear due to cost effectiveness. A conversion to rear disc can be done, however you will be looking at a rather expensive venture, not to mention the problems if you have an ABS system. Sans an ABS, you would need a new master cylinder, calipers and rotors for the rear, and some method of fabricating a caliper bracket. This shows that a conversion would be quite expensive.

    The correct spelling is DISC brakes. Wikipedia: http://en.wikipedia.org/wiki/Disc_brake

    I fail to see why you would need a new MC or how ABS would be affected or of any proportional issues.

    True. When I hear "Disc brake conversion" I am thinking like the conversions we did on the 67 Camaros all the time where the entire brake system was upgraded.

    Yeah I thought it would be a propotional issue. But i noticed that the smaller sports cars have all around disc brakes, just wondering wether its worth the time while i replace my front two rotors and pads. Meanwhile, it would look pretty cool having red calipers and sporty disk brakes all around. I would'nt call it a "ricer" mod if it actually increases braking performance.

    Pretty interesting conversion kit. The reason many conversions require a new master cylinder is the bore length and piston travel for a disc is not the same as that of a drum. A disc/drum brake system has a "residual valve" in the master cylinder where the drum brake feed is. Less fluid is needed to apply a wheel cylinder (drum brakes), hence the need for a different master cylinder. Not saying this is a golden rule, but every conversion I have done (Though it has been a couple of years since we did one) has needed a replacement master cylinder because of the amount of fluid flow.

    Very interesting. This sounds like a huge project, and costly. I would have to make alot of custom upgrades it sounds like. Unless their is a kit out their already that is compatable and includes new master cylinder etc..

    Yep, you have it backwards. It's easy to step down pressure from the MC but not to increase flow.

    Time for you to learn the proper industry terminology before attempting to disparage others online.

    Interesting, is this "residual valve" something that can be replaced/removed or is it built directly into the cylinder?

    Like this ?? Wikipedia isn't automatically wrong because it's wikipedia. I wouldn't take it for gospel...but in this case- Doens't matter where you look...DisC works just fine.

    And mjp is here- No one else needs to comment, unless they tried the swap too...

    OK, per Merriam-Webster dictionary: http://www.merriam-webster.com/dictionary/disc%20brake

    And per Webster-online dictionary: http://www.webster-dictionary.org/definition/disc brakes

    Anything else???? :D:D:D

    And in case you are wanting to delve even deeper, the DISC brake system name was derived because of the DISC rotor. The name DISC rotor is derived from the word "Discus" which lends it's shape to the rotor.

    SOME master cylinders can have this residual valve removed. I do not know which ones.

    So, hypothetically speaking, you could remove or possible drill out the valve (depending on construction of course).

    True, depending on construction. You would need to find out if the Master cylinder has the same bore diameter and stroke for both pistons. If they were the same, then removal of the residual valve could work.
