It's time to my brakes to be replaced, but instead of just putting new rotors and pads, I'm going to go with a 5 lug conversion... I do have some questions (yea, I've done my reasearch).

I can't afford to do the rear discs just yet, so a rear drum kit from latemodelresto will suffice. From what I've heard this is a pretty easy bolt on kit. No modifications to the parking brake, no new master cylinder, no prop valve, correct?

I plan on running some cobra calipers in the front with some healthy sized disc brakes (to make up for the drums in the back). This is going to be a street car, so I don't need strictly racing items.

I need to fish around for parts, but what do I need for the fronts?

spindles, hubs, calipers, rotors, pads... What else? Do any of these parts need to come off a specific year to be compatible with my 92 and the cobra calipers I plan to use?

Thanks guys...

If you are going to put cobra disks up front, you'll need to do the prop valve mods, and possibly a new master cylinder and booster as well.

A a mininum, you'll have to gut the stock prop valve and run an adjustable

Any guides on said modifications? There are almost none floating around for brake conversions... And if they are they are vague and incomplete.

Dugger Racing - Mustangs and a whole lot more!


He does rear disks here, but same thing.


If you go with a set of 99-04 Cobra/Mach1/Bullitt calipers, you may not need a new MC. The 40mm calipers have a similar fluid surface area as the stock 60mm caliper.


If you go with 94-98 calipers, your pedal will be harder.


But you still may need to change it

The bullitt wheels won;t bolt up the the ranger rotors. That;s the problem with them. The hub of the rotor is so large that a lot of SN95 wheels wont fit

Click to expand...

you do NOT need to gut the valve or run an adjustable one for front cobras only, you WILL want to get a bigger cylinder and booster though, along with a 3-2 port conversion.

when you go rear disk, thats when youll need to do proportioning valve mods.
