Rotor 4 Piston Forged Aluminum Caliper Brake System for DRUM Spindles
Disc brake conversion kit for 1964-73
Mustangs.
Pictures show system mounted to
our optional Big Spindle (not included in this kit but highly recommended for
serious street or track cars).
Using only premium
components, this complete 'turn-key' brake system offers the highest
level of performance available for 15" wheels. Using heavy duty
directional vane 12" x
1.25" rotors mounted to an aluminum hat this system offers great weight savings
and exceptional cooling. Stress flow forged aluminum calipers with 4
stainless steel pistons accept .800" thick pads in a variety of compounds. Our
custom spindle bracket requires no modification to your DRUM spindles and enables
the kit to fit popular wheels.

Caliper
Specifications: |
Description: |
Forged Aluminum 4 Piston |
Type: |
Fixed |
Number of Pistons: |
4 - Stainless |
Piston Size: |
1.62" |
Construction: |
Stress flow forged from premium grade
aluminum alloy billets. This process re-aligns the metals
internal grain structure to flow within the contour of the caliper
body. This process eliminates the stresses and interruptions
to the internal grain structure that occur when machining a straight
block. This results in a stronger and stiffer caliper. |
Pads: |
Continuing the
performance trend of this system, this caliper uses a huge pad.
Each pad is 0.800" thick, has an area of 8.2 square inches and
a volume of 4.9 cubic inches. That is almost as thick as a stock
Mustang rotor! Thick pads not only last a long time, they
offer insulation from the heat of the rotor transmitting to the
pistons and ultimately the fluid. Pad changes are super easy,
simply remove the center bridge bolt and pull out the pads.
Compound Information
Street:
- Medium friction, smooth engagement, low abrasion.
- Flat torque curve. Maintains a coefficient of friction
between .40 from cold peaking at .45 around 700F degrees.
- Beds quickly and provides fast response without excessive
abrasion.
Track:
- High friction, smooth initial response, low wear rate.
- Medium to high friction with good cold response.
- Smooth, predictable engagement.
- Long wearing pad in the middle temperature ranges with only
moderate wear in sustained high heat conditions.
- Peak coefficient of friction of .63 is reached at only 400F
degrees and is almost flat all the way to 1300F degrees.
|
Finish: |
Powder coated bright red or gloss black
- other custom colors available. |
Notes: |
Each caliper is
equipped with replaceable stainless steel bridge plates. These
plates eliminate the bridge wear caused by pad gouging and extend
the service life of the caliper body. The spring-loading action of
the plates also eliminates pad rattle and dampens the vibration
harmonics that contribute to squeal under braking. Other standard
features include high-temperature, square faced o-ring seals for
positive sealing, controlled piston retraction, and long service
life in high heat conditions. Stainless steel pistons are used to
resist corrosion and retard heat transfer from the pads. Two-piece
bleed screw assemblies provide long, reliable service life and are
easily replaced if necessary.
Caliper is mounted rearward of the
spindle upright (trailing). This position makes routing brake
duct hose in from the front of the car super easy.
Use 1-1/8" bore
master cylinder for perfect pedal height/pressure like #260-8556. |

Why use such a large
rotor? Well, simply put, heat. The friction created by
braking creates heat and the more and harder you brake the more heat
is generated. All that heat has to go somewhere and if the
'heat-sink' (rotor) gets so hot it can no longer absorb heat then
the heat will migrate to other components.
These other components will include brake fluid and wheel bearings,
not places you want increased heat. The problem with large
rotors is weight. All that weight is unsprung which will
affect suspension performance and increase stopping distances.
The rotor we use in this kit provides
the best of both worlds. Increased thermal mass due to its
diameter and thickness yet lighter weight when mounted to an
aluminum hat. In fact, the rotor, aluminum hat, hub and stud
combination used in this kit is 3lbs lighter than a standard
1970 Mustang rotor! Additionally the increased width of this
rotor allows the cooling vanes to be wider resulting in more airflow for
cooling.

As one judge, Geert Jan Schellekens, Principal Automotive and Industrial Designer at SABIC Innovative Plastics, said; "From several hundred entries to 20 finalists in a day's time - what could have turned out to be a cumbersome process, if not a bureaucratic nightmare, actually became an intensive yet fun session with many intriguing and interesting interpretations of the contest brief - fuelling some lively discussions!"
Another strong impression from judges was also of the variety of design entry and the effort that had been put into them, as Dale Harrow said: "I'm very impressed with the standard, and particularly with the diversity of entries to the contest". Derek Buckmaster,Global Market Director, Body Panels & Glazing for SABIC Innovative Plastics, said: "I was surprised by the depth of thought which the entrants had put into their designs to meet the diverse needs of the three 'milenniumites' described in the design brief. The designs displayed numerous approaches to meeting the environmentally-friendly and light-weight goals."
All designs were considered relative to the Assessment Criteria a critically important part of the contest, created to ensure as much fairness in the process as possible and detailed in the Contest part of Car Design News.
