When it comes to brake pedals you have some choices.  This
page was conceived to help you navigate those choices and
make a good decision on what is best for you.  

Brake pedal design falls into two main categories, under-floor
mount and under-dash mount.  Below we have compiled some
info for each style in regards to the AD/S10 frame swap.

For you 54-55 1st Series owners there is also a warning.
BRAKE PEDALS?
UNDER-FLOOR MOUNT

The under-floor pedal assembly for the S10 frame swap is the
hardest to design and install.  The under-floor pedal keeps the
stock appearance and feel.  If this is the style pedal you want to
run then you have a couple basic choices shown below.  With
all
the under-floor options you will need to manufacture a mount to
adapt the aftermarket AD pedal assembly to the S10 frame.

  • New assembly that uses your stock pedal arm
  • New assembly that comes with it's own non-stock looking pedal arm

Which one should I use??

UNDER-FLOOR MOUNT FOR USE WITH STOCK PEDAL
UNDER-FLOOR MOUNTED PEDALS
UNDER-DASH MOUNT

The under-dash mount pedal assembly for the S10 frame swap
is the easiest to install.  This style pedal comes in one basic
design.  This pedal assembly triangulates the pedal, firewall
and dashboard for exceptional strength.  This is the choice of
nearly all new car manufacturers.  The down side to this type of
pedal is that the master cylinder and booster assembly are
inside the engine compartment and it takes up a lot of space
under the dash.  It doesn't always look great and can cause
clearance issues but it sure is easy to top off the fluid
compared to an under-floor mount.  There are two types
available; 1947-1953 and a universal style for 1954-1955.1 (1st
Series).  We prefer to modify the 47-53 pedal to mate up to
the 54-55.1 dash.

THE SO-CALLED
"NEW PART"
WARNING!!
Beware when ordering the under-dash mount pedal assembly for the
54-55.1 GM trucks.  It is our understanding that the actual
manufacturer of the under-dash mount pedal assembly, sold by most
retailers, has ceased production of the 54-55.1 (1st Series) pedal
assembly as shown in the advertisements.  

Many retailers have NOT changed any of their advertising to state
this fact and their online systems will allow you to order the pedal
assembly without informing you of the fact that the part has been
changed.  

As an example, we received the pedal assembly pictured below when
we ordered online through one of the largest classic performance
parts suppliers. When questioned, the companies' customer service
department stated this is the "new part."
This "new part" looks
strangely similar to their
universal brake pedal assembly.  

The "new part" does not "triangulate the pedal, firewall and dash"
and will not make "the entire assembly extremely rigid" as stated.  
Firewall failure from repeated pedal applications could eventually
cause a
catastrophic firewall failure! DO NOT ATTEMPT TO
INSTALL THIS PEDAL ASSEMBLY.  THEY WILL NOT ACCEPT
IT BACK IF YOU DO.  PUT IT BACK IN THE BOX AND SHIP IT
BACK ACCORDING TO THEIR RETURN POLICY.  If you do get
stuck with it you will need to manufacture braces to connect the pedal
assembly to the dashboard.  Also, be aware that the "new part" will
not allow use of the cowl vent actuator without modification.
We prefer to modify the 47-53 pedal to mate up to the 54-55.1 dash.

NOTE:  Specific application pedal assemblies shown below can NO LONGER be ordered directly
through Pirate Jack.  They do not carry these parts anymore.
Thank you to Pirate Jack for allowing us to use their photos for this page.
This is not a Pirate Jack part.
NOTE:  It is the opinion of ADE that trying to reuse the stock S10 pedal assembly and modify it
to work under the AD dash is more trouble than it's worth.  If you are going to use the under
dash style pedal it is much easier to install the aftermarket pedal, which is inexpensive, than to
try and force fit the S10 pedal.
WE DO NOT SELL BRAKE THE BRAKE PEDAL ASSEMBLIES SHOWN BELOW.
