Problem Solving Hot Rod Chassis Parts Since 1978
Brake kit for 1974 -78 Mustang II and 1974 – 80 Pinto/Bobcat spindles. This kit adapts larger 11″ Granada rotors and 1982 – 92 Camaro (or equivalent) calipers for a simple, effective, and inexpensive brake upgrade. Some 14″ wheels will clear the calipers. 15″ wheels will clear. The 1975 – 80 Granada rotors move each wheel out 1/4″ from stock Mustang II rotors.
Welded kit includes all hardware included in the ready-to-weld kit.
WELDER SERIES’ PARTS ARE TO BE ASSEMBLED AND INSTALLED BY QUALIFIED WELDERS. THE PURCHASER OF WELDER SERIES’ PARTS MUST ESTABLISH THE SUITABILITY OF THE PARTS AND THE QUALIFICATIONS OF THE PERSON WELDING THE PARTS. WELDER SERIES PARTS, WELDED IMPROPERLY, COULD FAIL AND CAUSE INJURY OR DEATH.
This kit includes caliper mounting brackets (driver & passenger sides are different – they will not fit on the wrong side), and mounting hardware. Use the hardware in the kit to mount the caliper brackets. DO NOT USE THE STOCK FORD HARDWARE – IT IS NOT THE SAME THREAD!! The photo shows the kit mounted on the passenger spindle.
The stock Mustang II dust shield must be removed from the spindle and discarded. The Granada rotors fit onto the Mustang II spindles using stock Granada bearings, seals, outer washers, nuts and dust covers. Stock Mustang II spindle nuts can be used.
The end of the lower control arm must be ground away for rotor clearance. DO NOT INSTALL THE ROTOR UNTIL THIS CLEARANCE HAS BEEN ESTABLISHED. 1/8 inch clearance is enough.
Use stock brake pads (#7070A or FMS #D154) for the calipers.
NOTE: The squealer tab on the inside brake pad must be bent 1/8” toward the rotor surface. This can be done by carefully tapping it with a hammer. The outer pad tabs may need to be bent slightly to tighten the pad on the caliper. This will keep the pads from squeaking.
Stock GM calipers have a lip around the brake hose port. Grind this lip and rotate the hose fitting so it clears the coil spring when the steering is at full turn lock. Be sure the brake flex hoses do not touch wheels, tires or any other parts under any suspension travel or cornering conditions.

Use a pair of 1974-78 Mustang II spindles as a fixture. This way the parts will be held in exactly the right place for tack welding.
The end of the threaded spacer (for the ½-20 bolt) should bottom against the slot in the plate. Take the tacked assembly off of the spindles to finish welding. Avoid getting weld inside the threaded spacer.
Be sure to read the installation tip sheets shipped with each kit.
Every customer is different. You’re different from the next customer. That’s why they’re called 'custom'ers. There is no formula, no equation that will work with all of you. It takes a different approach to everyone to determine how best to serve anyone. Some people need videos, some people need descriptions. Some people need us to weld it together. Our approach has been, and will always be, to serve each of you where you are and to treat you the same way we would like to be treated. We officially opened the doors to Welder Series in 2005. That doesn’t sound like very long, because the product line has been percolating for over 40. Paul Horton began developing and building many of the parts we still manufacture when I wasn’t yet a twinkle in Dorothy’s eye. Thanks very much for your business and support over the years.

Note DW and Paul Horton at Welder Series absolutely rock and were quick, prompt, by far the best communication I’ve had with an online vendor in a LONG LONG TIME… (Sorry but their response time was bar none awesome). Very rarely do you find the level of dedication to a customer, communication, and a rewarding experience for both the buyer and supplier. I bought a pedal assembly a bit ago, and that experience automatically ensured that I will source Welder Series before I search for another vendor. Paul and DW have it together and will make a solution to your problem… and probably at the best price around to boot.
I have purchased a few of the products that Welder Series offers and been pleased each time. The products are as advertised and they ship in a timely manner.
I am also impressed with their customer service. I asked them if they had a brake pedal kit (mount, pivot, pedal, bushings, etc) for a right hand drive application. They did not have a kit per se but were able to put together pieces from their catalog to make one I could modify the Master Cylinder mount to make it face the other way (I had to cut the top off and weld it back on facing the other way, cheaper than ordering a one off part, and I don’t have a way to bend metal that thick, everything else fit up as intended). It worked as they described.
I just finished installing a Welder Series rear sway bar kit over the weekend. My all-steel ’35 sedan handled in the traditional “scrape off the running boards” way… even with a front sway bar. The kit went together nicely, everything fit perfectly and now the car goes around a corner 100% better… no more extreme lean. DW was a huge help in putting together a little bit different kit for me since I am using a tubular rear crossmember and also made some suggestions that really helped in the fabrication. You can depend on these guys… they are “for real” hot rod guys that offer really cool products. I’ll post a picture or two when I get the chance to put the car on a hoist for a better photo op. Thanks DW & crew.
