How-to; DIY 2 pot brakeupgrade

[Kirk525]

Ok my BG is an 94 LX with all 4 dics brakes.so you're telling me if i get the 99-03 BJ 5 lug dics brakes all 4 it will work on my 94 BG.(onemore thing do i need to get the hold entire struts with it or just the hubs alone thanks alot).im looking forward for you're help.

if you are looking for just the upgrade to 5 lugs then take the hub from one of the mazda cars with 5 bolt pattern and put that hub in your nuckles i know one of them bolts right in just don't recall which

I can't say for sure, but I can say that all models of BG and BJ use the same front wheel bearing so I'm pretty sure that any of the front hubs would interchange. Ther rears are a little trickier because the BJ rear disk brakehub is clearly larger than the drum brake one...which is the same as the BG one for all models. But the spindle is the same for drum or disk brake BJ's so I think that the 5 lug hub will fit on your BG but it won't be known for sure until someone checks.

EDIT: Check that...the BJ with rear drums uses a different rear spindle than the BJ with rear disc...which makes sense. The spindle OD and bearing may still be t he same, but I am not sure at all if the 5 lug hub will fit ont he 4 lug spindle. Someone will just have to try it.

just as a small update to my original post
i've found that a certain toyota, yet to be named!
has 4x100 275mm x 25mm thick rotors
and basically has the same hat dimensions as the mazda BG

i will confirm fitting shortly (1 month or so)

that alone will stop most any Mazda under 1200 kgs at the track

I'm guessing AE101 rotors?

[300BHPZE]

this is virtually identical to the BG rotor only 11.6" in diameter...just FYI



The Mini also came with 276mm and 280mm I believe.

For comparison...

what is the "hub reg" and "bolt size" talking about?

what is the "hub reg" and "bolt size" talking about?

Hub Reg is the size of the center hole where the spindle comes through. Bolt size is the size of the lugs. The Mini has 1/16" larger lug nuts than the BG/EC but that should not be large enough to cause a problem. The hub hole is larger so that's fine. If it was smaller that would be an issue, but larger is fine.

AE101 and AE111 superstrut only! , they have two pot brakes too .

but the normal ae101 are the same size as BG so must be a very close upgrade

hi to all, i have found whats look like a 93-97 626 in my country (very rare to find one over here).
So will the brakes from the 626 work on mine BG? ive read trough the whole thread and didnt get it, my bad

any help will be apreciated

[Mazda_Powered]

nope will not work, sorry!

[300BHPZE]

The brackets from the 626 would allow you to bolt the calipers from a Subaru to the spindles of a V6 323F... Which are a direct swap to any BG or EC chassis.
