Will these rotors work?

Baer Cross Drilled/Slotted/Zinc Rotors

Baer Rotors (new)
These are BRAND NEW Baer Rotors 13.125 x 1.25''
7.625 Bolt Circle / 12 bolt
1.25
These are slotted,cross drilled and zinc coated

I have a 72 C10 with stock discs' up front, and i am just looking for an upgrade.

I'd be interested in knowing this as well.

I'm watching too

If the ones in the pic are the ones you are wanting, then no it won't work. These trucks have the rotor and hub as a one piece assembly.
On a side not, the drilled rotors like to crack. Slotted is OK, but I wouldn't do the drilled ones personally.

[smokekiki]

I've never had a "good" drilled rotor crack.You shouldn't need to worry about Baer rotors cracking.

[Longhorn Man]

While yes, the better ones don't crack as much, they still crack 10 times easier than solid or slotted ones.
Not to mention, it may just be our lathe, but I know we can't turn them, might be no one can turn them...I don't know. I'm just letting him know the draw backs of these rotors.

[GreyHoundSteve]

Ive seen cracked drilled rotors as well but they were less reputable brands.

[smokekiki]

Drilled rotors can be turned.You can't take to much at one time.A good set of drilled rotors like baer or brembo should only need the surface cleaned up.The drilled part is to disapate heat to stop warping.The slotted part is to clean the brake dust away.Baer garrenties a lot of,if not all of their rotors against warping for life.

[smokekiki]

That rotor needs at least a 17"wheel.

[Smokin72on20s]

this is what the seller had to say "well you have to get a bracket from baer to relocate the caliper . the rotors are 13 inchs thes big ... you have to cantact baer for adapters for calipers and for the hub"

[68LSS1]

I've got Baer 13" rotors and their PBR two piston calipers. Their kits come with a hub that is held on the spindle by the axle nut. The rotor slides over that and then the caliper is put on. I believe this is a semi floating design. Those look like full floating rotors. 15" wheels will barely clear the rotor by itself. I put some 16" Vintiques I picked up cheap to get the frame mobile and it's not even close. 18" wheels should be good but you'll have to do some careful measuring with the 17" wheels. A spacer could be required either way. There is a picture or two in the link in my sig. Keep in mind that mine are on the Fatman Mustang II suspension. The cross drilled rotors can be turned but you will have problems finding shops that will do it. As far as the crossdrilled holes you will never put the rotors through the extremes that the road race cars experience that do occasionally crack them. Notice I don't have slotted or crossdrilled. I'd price everything out because I'd be afraid by the time you put the kit together it may cost more than buying the complete kit. Check various racing forums as there are usually some doing GP on Baer stuff.


Just realize the slotted/drilled will not net you better braking. It's a bling-bling thing.

I'm just curious, but what are the advantages of having slotted and cross drilled rotors? Do they work better or is it just for show?

Thanks,

In performance driving,like rally cars,the holes reduce heat,and the slots are to channel the brake dust away.That is why slots are curved to the outside.You run them on street cars for show.

Thanks smokekiki.

It depends on the bit in your lathe too. If you are using the old style bit's that have a point on them they do like to chatter. If you have one of the newer style bits that has a oval shaped blade as a cutting tip they work much better....
