Doing my front brakes and realized my new pads don't match my old ones. Seems close enough in size however the holes for the pins are too close together. I've had the truck for 3+ years and vaguely recall the previous owner mentioning something about a Landcruiser brake upgrade.

Any ideas on how to identify the calipers or old pads? The part number on the steel shim is mostly gone. I've included pics.

Truck is an '85 SR5 w/ 22re. Old pads were on when I purchased the truck and new pads are Powerstop Z23-137.


Caliper - end

Old pad - back

Old pad: 4-1/2\" pad width

Caliper - front

Caliper - back

Old pad: 4-1/8\" pin spacing

New pad: 3-5/8\" pin spacing

New pad: 4-1/8" pad width

 

Brushed off the back of the caliper and found S12W stamped into it, so I guess that means I have V6 calipers! Serves me right for not checking before ordering pads I guess.

 

Looks like he did a vented rotor upgrade. At the parts store look into say an 87 4x4 IFS for application. The IFS trucks had the vented rotors and a thicker caliper.

 

its a V6 caliper .. from 88-95 truck or 4Runner

 

V6 calipers and also rotor thickness changed in production sometime in 1992 I believe.
Looks like the OP might have the early type.
