Am I seeing something? Disc brake isssue

Hey all,

I have been unsatisfied with my rides brakeing ability since day one. I have a 57 chevy truck. sbc, 700r4, mustang2 power assist disc brakes up front and drum rear. I figured with that kind of set up, i'd go through the windshield when i stomped the brake. not so much.

I was looking at this snappy pic I took of my truck when I noticed that my caliper sits about 3:00. If memory searves me correctly, it should be closer to 1:30-2:00. Could this be aiding to my crumby brakeing?

I have a few other brake threads out there too.

Thanks.

I do not think the caliper location will add or subtract to the efficiency of the brake power. It has more to do with bleeding. Disc brakes really do not lock up the tires, do not get me wrong you can get that, big rotors 6 pistons. You want more grip look at lager rotors and at least 4 piston.
One other little note you say ''mustang2 power assist disc'' calculate the weight difference between your truck and a mustang, that is a clue. Brake package sounds like it is not up to the job.

I don't think the idea is to put your face into the windshield when you upgrade your brakes. I'm sure your overall stopping distance has greatly improved and with the fronts being discs, they're much less fade-prone. Also, remember that good stopping power relies on good tires too.

I based that statement on something I was told at tech school. I dont fully understand why caliper placement is vital, but the fact that ever assembly car has the caliper clocked at 1:30-2 viewed from drivers side.

Your caliper are in the right place... And they are right about the location...It really doesn't make a difference where they are.... What size rotor's do you have up front ??

Good brakes are a function of the total package. If you are using the tiny MII rotors, you are not getting enough braking surface on the front where about 65% of your stopping power is generated on your pickup. Most MII kits have either GM 10 7/8" front rotors or Ford 11" rotors on the front. If you have either of those on the front, you should have a matching (balanced) master cylinder that is for a disc-drum set up. You also want to make sure the plumbing is not crossed up ie, feeding the front from the chamber designed for the rear. And last, if the MC is under the floor, you will need the appropriate residual valves installed. Not having the valves installed usually results in a poor pedal or pumping action to get a pedal, but also can cause poor braking on the front.

I'm afraid you are. New cars have calipers anywhere from 9:00 to 3:00.

It is all about bleeding the brakes, that is it in a nut shell. Schools are not real life, close bit no cigars.
