D-Series Caliper Brackets


Dodge had a great deal of interchangeability with their brake parts for their trucks. This gives us an opportunity to do some part swapping. The Dodge Dakota shares the same spindle upright as the D-Series trucks from 1973 through 1993, this includes the D100 and D150 and D250 with 3300# axle. These caliper brackets allow you to use the Wilwood D52 (PN 120-10936) or the large platform 1970’s GM Trucks and other vehicles that use a 1 1/4″ rotor.

Please read the product description below in choosing which bolt pattern you want to run.

Sold as a pair.

You will need to use the following rotors with this caliper bracket set. These all are an 11 3/4″ diameter rotor that is 1 1/4″ thick, vented and use bearing sets: SET 11 (Timken) or A18 (National) inner bearings and SET 16 (Timken) or A16 (National) outer bearings, same as the Dakota from 1987-1996.

Bolt patterns are as follows:

D100 Raybestos # 7034R is a 5 on 4.5″ Bolt Circle 11.75″ Rotor *REQUIRES MACHINE WORK*

D150 Raybestos # 7009R is a 5 on 5.5″ Bolt Circle 11.75″ Rotor

D250 (3300# axle) Raybestos # 7040R is an 8 on 6.5″ Bolt Circle 12.81″ Rotor

PLEASE check clearance between the lower control arm and the rotor. In some cases with dropped spindles and lowered springs or airbags, the lower arm can contact the back of the rotor. If you have this situation, you can trim the flange off the lower control arm to provide more clearance so there is no contact. 

GM Calipers to use:

Raybestos # RC4214 LEFT

Raybestos # RC4213 RIGHT

Wilwood D52 Caliper set #140-11290

(If using the D100 rotor, the inner bearing boss needs to be machined to 63mm and the seal boss also machined to accept the Dakota/D150 seal. We are trying to get a conversion bearing available for future usage. )

Brian also adds:

The rotor you listed for the D100 Raybestos 7034 will work without machining. It uses the A18 inter bearing. The 1980 down rotors need machining because they use the A17 inter bearing. Around 1981 Dodge changed the spindle to use the A18, but still had the 4.5 bolt circle on the rotor. They changed to the 5.5 bolt circle in 1984 and still used the same A18 bearing spindle. There is a lot of misinformation on this on part store web sites. Also full size Dodge cars in the late 70s used the same 4.5 bs A18 inter bearing rotor as the 81-84 trucks aka rebestos 7034 rotor.

I been all through this mess because I own a cnc machine shop and I make early and late (Dakota) front hubs to mount 13″ Mustang Cobra rotors on D100-150 using Wilwood 6 piston calipers.

You guys make good products. I am about to help a friend install one of you Dakota front suspension kits in his 60s Ford truck.

Keep up the good work.
