Is it possible to do a rear disk for the xB other than an extremely expencive, and imo, overkill big brake kit? Any donor car (goin back to my honda days) that will bolt up to the xB rear assy? Thanks!

hotbox05

nothing bolts right up but it's been done a few times. corolla gts rear setup with an adapter plate and such.

really, if your not goiing to race your car, or run EXTREMLY large wheels, there isnt a need to put 4 disks on the car...

xBtenchu

No need, there just fugly.

nothing bolts up...and you would loose the parking brake if you go with the BBK inthe rear.

and for looks, the drum is easier to keep clean and it performs better than disk....(how many big rigs do you see running disc's??)

scsi

how many race cars do you see running drums?

not saying the xB is a race car, but its not a big rig either, it weighs less than the late celica gts

Well if Expeditions have 4 wheel disc brakes now doesn't that say something about how well drums work?

here's the old thread about the kits, and concerns... still looking for the tech writeup of the actual DIY conversion...

no...it talks about how manufatures try to cut cost buy using a less expesive method.
and how the market pressure is forcing unsafe production decisions.

and for the race cars...did you ever see what their brakes are made of...not the typical steel rotors...they have cooling systems for the brakes...they will toss out the parts after a race...if you tried to do what race cars do...your brakes would glaze over, the pads would catch fire and you would crash from system failure.

i am not saying disc brakes don't work. i am saying that drums are getting a bad rap. they are a very solid and efficent system.

you can have a larger swept area with drums. they perform just as well (if not better) in most conditions. the only reason i am hearing on why they should be changed is they look ugly.

Thanks. I can't ever get a good search on this forum software. it seems no matter what word I put in the search bar, I get the same 100000000000000000000 results. Most that have noooo relevance to what i'm looking for.

cut cost by using disc brakes? drum brakes are WAY CHEAPER.

dgHotLava

not really...

think of how many little parts there are in the drum setup...springs, pins, shoes, backing plates, clips.........
more than double of a disc setup. and you have to pay the wages of the person putting them together....and then they ned to be adjusted before use....

this make drums more expensive than disc from the manufacture standpoint.

xA_Factor

This is the truth. Drum brakes are cheaper to produce than disc brakes.

dgHotLava

wrong.

maybe just the drum. but if you look at the whole system and all the little parts and assembly time...drums cost more.

xA_Factor

The caliper and the rotor-disc alone cost more than a drum assembly...this I promise. It's a cost-up for the manufactures not a cost-down. A higher component count does not always equal a higher cost.

Besides, if it were cheaper, every xA, xB, Echo, Yaris, Corolla, Civic, Foucus, ect., ect. would have rear discs.

cherryBox

my opinion is that while the cost of production may be more, it's cheaper to leave the drum brakes on the car than to upgrade the system

dgHotLava

still wrong...
consider ALL the factors and the drums are more expesive. more labor, more parts, more machining...

but whatever...you think what you like, i'm comfortable in my knowledge (and experiecnces).

drums are a lot cheaper

if you have the spring pullers you can swap drum pads quicker then disks

or at least i can

The DISC vs DRUM discussion has intrigue me so I did some search on the web. Here's one article I found. Check it out ...

good find proves it once and for all

anybody remember the really old school mini's

they use to race with 4 wheel drums

makes a good point that not to many people think about, 60-90% of the brake power of a car is coming from the front disks
