Will these parts fit

[Lefty]

Now, I'm lost. @Lefty If you already have 10" drums, are they not finned ( smooth ) ? Are you asking if 10" finned drums will fit your 10" brake assembly?

Yup. But I'm told they won't make much difference anyway.

Big Ole aftermarket four piston calipers on the front.

Sounds good too.

Those finned drums will run cooler... and with that... perform better. They are simply a superior part in comparison.

I ended up keeping the set that wouldn't fit... they will get machined and put in service on my truck. They would shine brightest in hills/mountain driving or towing.

I did this on my '87 Nissan D21. Swapped the single piston Calipers for the "V6 truck" Dual piston calipers.

Very well. i will continue to look for them.

Can you recommend a vendor for 4 piston calipers?

Whatever you look at, make sure they are compatible. It would suck to get the calipers and needed bracket and find out they don't bolt on. You might need to up size the disc rotor as well. Depending on the size of rims you have, there may be a fitment issue even if the calipers bolt on to the truck. The bigger rotors my 2011 has just barely fit in the 15" rims and only certain rims clear the calipers. So tread carefully.

I’d be surprised if you find anything that is a direct replacement.

I've got 15' rims too. Do you remember the parts you bought?

You misunderstand and/or I didn't word things properly. They are the factory brakes. At some point, Ford up sized the front rotors and pushed the limits on what fits in a 15" rim. You may already have the bigger rotors on your 2003. Mine are 12" rotor discs. I think the older models has 11.2"

Thanks for clarifying. I will check.

Unless your towing trailers down mountain passes I'd probably just go with "performance" pads/rotors/shoes and call it a day.

I'm willing to bet that if you could somehow quantify the difference that the finned rotor upgrade provides... it really wouldn't prove to be much of a difference in regular operation.

I'm thinking the same. I'm not the type to blaze any new trails in Ford Ranger modifications. My own skill levels will never go further than direct bolt-on. Still, thanks to you and the other members here, I've come quite a long way. And it is a much better Ranger after only two years.

I’ve heard that about the drilled rotors. If the holes are chamfered, the chances of that happening is greatly reduced. I never had a problem personally but I didn’t go cheap and all of my rotors were chamfered.

I thought they all came chamfered?
