confirm my thoughts please! - 04/12/13 12:29 PM

I'm re-doing the rear brakes on my Dakota, since I'm putting in a new axle with better gearing (bought the whole axle cheaper than I could have bought just the gears)

this time though, after learning something on this forum regarding the whole moment of torque and caliper positioning....I at least wanted to LOOK the part of a super car, even if it is a fat, nose heavy pick up truck

so, I'm now mounting my rear calipers vertical, on the front side of the axle:

I think I messed up though... to keep the bleeders up, I switched the calipers side to side. simple right? but the viper calipers have 2 sized pistons in them, and I think by flipping them, I just put the larger piston on the leading edge vs the trailing edge.

(I have to go look to verify this, but I'm pretty sure that's what I'll find)

the correct way to do this would have been to remove the bleeders and the cross over tube and flip them top to bottom, right?

All I can speak to is you need the small piston first and the big piston second. So yes, flipping sides would put it backwards and cause abnormal pad wear.

I didn't know flipping the bleeder and hose sides was an option. Do people do this with success? That could be really useful for me if I need to change the rear caliper sizes.

I haven't checked yet, but I assume the threads for the bleeder screws on the top side are the same threads as the cross over tube on the bottom side. if they are, then I should be able to flip them around to make it work.

I am no help here...but I love the look of the blue calipers!!! is that paint or powdercoating?

Thanks. Its Automotive paint. BC/CC, same color code as the truck. With the clear being hardened, it allows me to hose it off w brake cleaner to clean off the dust.

I would say moving the bleeders/transfer tubes should work. ....or mounting them as is on the rear instead of the front?

yea, I don't want them mounted on the rear though.

I want my rear axle calipers to be in the front like this:

Since these calipers are identical swapping bleeders and crossover allows you to put them where you need as long as the pistons are oriented properly. Just don't break the crossover tube as they are metric bubble flare and not avail serperately.

You could always leave the bleeders on the bottom and just use a vacuum bleeder prior to actually bolting them on the truck to bleed the system. Just vacuum bleed them with the bleeders facing up.

true. or remove calipers and bleed them while off the truck. but, that's more headache than I want to deal with, since it shouldn't be any problem to flip around the bleeders and cross over tubes

well, it looks like I'll have to do my bleeding procedure with the caliper unbolted from the bracket. I tried to remove the cross over tube, but the factory powdercoat under the paint I did is too thick/strong, and it's just going to round off the tube nut. I even tried to take a scribe and break the seal on the powdercoat, but it wasn't enough.

A lot of "looks" in this thread, it "looks" to me you should move the calipers back to the rear upright position, you tried, but if one time in the future you hesitate to bleed the brakes because they have to be removed and inverted first, "looks" and polar moments etc will take a big back seat. Besides, moving the drivers seat 1/2" back would likely impact the polar moment more then rear caliper location, if you weigh more then say 200lbs

Have I confirmed anything?

yea, you proved that your opinions are still worth what I paid for them.

you make it sound like brakes need bled every time you take your ride out of the garage.

I put these brakes on originally last year, and have driven them 2,000 miles since. haven't once had to re-bleed my brakes.

If I ever do have to re-bleed them, 2 bolts and they're off and free in my hand. takes me about 45 seconds to remove a caliper, which, is really nothing when you consider the time it takes to jack up the vehicle, jack stand it, remove the wheels, etc. when bleeding the brakes.

and yes I weigh more than 200 lbs. but no, my seat is not moving. this is a regular cab pick-up truck, and I'm 6'4" ....it's already against the back wall of the cab!

So the check is not in the mail?

Thanks for posting the results! sorry it didn't work.

when/if the time ever comes to have these rebuilt, I'll probably swap them for reman'd ones and coordinate ahead of time, to try and get them with the tubes and bleeders not installed, so I can set them up as I need to.

but since these calipers are still working fine and show no signs of leakage or siezed pistons, I'll just roll with what I have, bleed them off the truck, then install them and forget about it.

Like I mentioned...how often are we really going out to re-bleed our brake systems?

I did a little searching on the subject and found someone who had to replace the crossover (and Brembo doesn't sell that, as established). He used this part number from Autozone: PAE308

http://www.autozone.com/autozone/parts/Brakelines-Brake-Line/_/N-8kp1m?itemIdentifier=85314_0_0_

So if you broke one removing it, you're only out $4.
