BB4 Caliper Question

[bmxicansd]

i grabbed a set of calipers off a bb4 prelude to test fit them on my accord knuckles w/ 11" wagon rotors. The only problem is the brackets have clearance issues, they basically bind on the wagon rotors. Are the accord wagon brackets different then the bb4 brackets? anyone experience this problem. any insight is greatly appreciated..

where do they bind?

id imagine they should be fine since the rotors are the same size as the prelude vtec ones. what stamp is on the brackets you have?

basically if i bolt them up they bind on the outside face of the rotor preventing it to spin. I can post the stamp on the brackets tomorrow.


btw hope you have merry christmas mike

You might have 23T brackets. I think you need to use the 25T. I could be wrong about that though.

I think the rotors might be of different thicknesses. Try cross referencing the part numbers on majestic for BB4 VTEC rotors and Accord Wagon rotors. Do the calipers too and see if they're the same. I think the calipers are identical, just not sure on the rotors.

I'm using all Acura Vigor brake parts and it everything bolted up fine to my knuckles

i think u pulled si calipers rather than vtec calipers. if they say 17cl14vn then they are si's and yes u need the vtec bracket too. all this info is in the brakes forum. do some reading its all there.

What a noob...learn to search!

If I remember correctly the BB4 should be running a 23t bracket. The wagons and 5th gen AV6 run a 25t bracket. Basically you need to find a 25t bracket to work with the wagon rotors or use vigor rotors to work with your 23t brackets.

Yes i just confirmed and yes they are the 23T brackets.

Thanks Losi..

haha sounds about right.. I barely drive my cb anymore yet alone have time to work on it. haha i did however replace the sway bar bushings

i got the 17cl15vn calipers with 23t brackets. haha

how about do a rotor over hub...and call it a day..take hubs out of the prelude knuckle and grind the out race down to fit our bearing...the caliper will fit onto the knuckle with no problems after check my sig...

[mndude07]

Yeah I just checked the 23T brackets should be the right ones, so your rotor thickness is probably wrong. BB6 prelude rotors or CB7 Wagon rotors should be the proper thickness. BB4 VTEC rotors may not be the same...

[Blk EX Coupe]

The rotor thickness is the same. The difference between a 23t and 25t rotor is the height of the rotor's top hat.
