These were my stock brakes. Look familiar?
This is not a brake job "how to". I'm going to assume you know the basics of doing a brake job from here on out.
What I found is that the 99+ V6 mazda 626 has larger rotors all around than our stock 93-97 MX-6/Probe. And same year 626.
EDIT: Stock Diameter for all front rotors between 93 and 97 and 98+ 626 4 cyl's is 10.2" 98+ 626 V6 front rotors are 11.1". Thats a nice .9" improvement. Rear is about a half inch larger than stock.
The part list needed is short and the cost over stock replacement parts is small. About $50 for me.
You will need ... the rotors front and rear for a 99+ 626. Auto zone PN 31255 front and 31256 rear.
The pads for the rear are identical to our stock pieces and our fronts will fit but the 99+ 626 pads are taller. PN DG755 front DG584 rear.
Rear
Front
Front rotors compared to stock.
And rear.
What makes this work are the caliper brackets from the 99+ 626.
they relocate the calipers out enough to clear the larger rotors.
Our stock calipers will fit perfectly in these brackets. EDIT: you WILL need the 626 front calipers as well as the brackets, if you use your stock calipers your rotor will grind against the caliper under braking[/i]
You will also need either the spare tire from the late V6 626 or a spare from another car that will fit over the calipers ie RX7 spares or many Ford and Chrysler spare wheels. Our stock spares are windowed and the lips of the windows will hit the caliper when the wheel turns but the 626 spare is a plain dish type steel wheel.
New front's mounted.
Rear.
You dont need to attack the dust shield as I did this one.^
The fronts fit with no problem. The rears will JUST fit inside the dust shield. After everything was mounted I went around the rotor with a screw driver and pryed the shield away till it no longer rubbed.
On a side note these are also used on the Mazdaspeed Protege. And the rotors are shared with the early mazda 6/3
LAST EDIT: All right! To sum everything up and be sure your clear on what you need without having to troll the entire thread ten times heres the breakdown of what you will need and what will and wont work based on 2 years of learning ....
The parts you will need are all from the 98-2002 Mazda 626 sedan with the V6 option.
You will need all 4 rotors, the front calipers and brackets, and the rear brackets.
The rear calipers are the same part number so you can use your stock rear calipers if you want or need to.
The simplest (though not allways cheapest) way to get all the parts you will need is to buy "loaded" calipers for a 98-02 626 V6 that will include the brackets and will simply bolt up like replacement stock parts with the 626 rotors.
They will come with pads but you'll proabably want to upgrade to performance pads and keep the parts store pads as spares.
The pads both front and rear will interchange, however the 626 front pads are slightly taller and have more surface area. This might not apply to all aftermarket pads especialy if manufacturers realise they can market MX6/Probe pads as 626 pads and save costs.
The rear pads are the same.
You can also use the 626 pads with stock MX6/Probe rotors/calipers and brackets to increase the pad area slightly. Or if you have a fovorite pad for your mx6 or probe and they dont make one for the 626 you can still use them with the 626 upgrade.
You will need a different spare tire for your car if you do all 4 corners. The 626 spare will work as well as several others.
Good luck and have fun
