Front Disc Brake Installation Instructions
These instructions s are for a variety or EMPI Front disc brake conversion ki ts. Please read this entire set or instructions before
proceeding with the installation. Any instructi ons that are Safety related are listed in Bold italic typeface and must be strictly
adhered to. This Brake Kit will not work with dropped spindles, will only work with stock style drum brake
spindles and must be used with 15 inch or larger wheels.
These step by step instructions should be read before you start to do any work and you should be able to understand them
completely . If you do not have the resources to do this installation then have it performed by a qualified mechanic. Failure to
follow these directions could result in damage to your vehicle or possible bodily injury.
Your EMPJ disc brake kit is designed to be used in combination with drum brakes . If you are going to install 4-Whee l Disc
Brakes, a Dual Circuit Master Cylinder will be necessary. EMPI Part # 1 6-9554 (Paruzzi Part # 3298), Dual Circuit - 20mm
master Cylinder, for all Beetles and EMPI Part # I 7-2808 (Paruzzi Part # 3243) for Super Beetles are available at your
EMPI or Paruzzi dealer.
To start. secure the vehicle on a level, hard surface. Block the rear wheels and set the emergency brake, loosen the
front lug nuts while the front wheels are stilll on the ground. but do not remove yet.
Elevate the complete front suspension off of the ground and use approved jack stands to support the
weight of the vehicle. (DO NOT use the jack only to support the vehicle)
Remove both front wheels.
STEP 4A : If you r vehicle is a I 966 or older beetle you wil1 need to remove the existi ng master cyl i nder and bolts: i nstall the
newly supplied master cyl i nder with the new longer bolt s and n uts suppl ied with this k i t (always bench bleed a
new master cylinder) . Reinstall the master cyl inder stop l light switch and metal brake l ines. Install billet alumi num
reservoir adapter wi th the alumi num seal and reattach the rubber hose from the brake fluid reservoir.
STEP 4B : If you are worki ng on a 1967 or newer beet le with a dual reservoi r master cylinder. you wil l need to remove and
replace master cyl i nder with the new unit furnished i n the ki t (always bench bleed a new master cy l inder).
Remove the front brake drum on the dri ver’s or left side, mak i ng sure you remove the i nner wheel beari ng and
old grease seal.
Loosen and remove the flexible brake hoses from metal brake l ine at the pan .
Remove the 3 bolts that hold the drum brake backing plate to the spindle. Remove the complete backing plate
(includ ing brake shoes and wheel cy l inder with hose).
Clean and i nspect you r d rum spindle, making sure that the spindle stub is in good condition. If the
spindle is damaged or shows sign of excessive wear, you should replace it before you install your new brake
Clean the surface of t he spi ndl e before i nstal l i ng the new cal i per bracket . Thi s surface must be free from anythi
ng that will cause the bracket to bind or not set flat on t he spi nd l e. Bolting the bracket to an uneven surface will
cause it to crack or break.
STEP 10A : 1965 and older beetles with link pi n front suspension will use the original l backing plate bolts to i nstal l the cal iper
brackets. If you do not have these bolts. You must use bolts with a hardness rating of 10.9. Install the bracket so that
the caliper is at t he rear of the spindle; the bracket should go on easily. DO NOT hammer or force the bracket
in place. DO NOT use bolts to “pull” the bracket in place. Doing this will cause the bracket to crack or
break. Torq ue the bolts to 25 ft.lbs.
STEP 10B: for 1966 and newer beet les with ba l l jo i nt front suspension, i nsta l l brackets with the 10 m m bolts ( 1 0 .9 grade)
supplied wi th k i t. I nstal l the bracket so that cal i per is the rear of the spindle. The bracket should go on easily,
DO NOT hammer or force the bracket in place. DO NOT use bolts to “pull” the bracket in place. Doing this
will cause the bracket to crack or break. Torque the bolts to 25 ft.lbs.
STEP 1 1 :
I nstal l the supplied wheel bearing races in the new rotors. (Be careful not to damage the rotor or races by
binding them). We suggest that the bearing races be pressed into the new rotors.
STEP 12:
Pack the new beari ngs wi th suitable hi-temp wheel bearing grease.
STEP 13:
Install greased wheel beari ngs and the inner seal in the new rotors.
STEP 14:
lnstall the new rotors on the existing drum brake spindle - using existing thrust washer and adjuster nuts. Adjust
to factory specifications. (Be careful not to over tighten adjuster nut. This will cause overheating of the bearings,
resulting in damage to spindle, bearings and rotor). Instal l the grease cap and speedometer cli p.
STEP 1 5:
I nstall the inner and outer disc pad, into the caliper. Note: The I n ner and Outer pads are different (See Below)
STEP 16:
Instal l the caliper over the pads. (Making sure that you remove and discard the spacers i n the cal iper pinhole .)
Install the mounting pins i n the caliper and put thread locker on the treads and thread i nto the bracket then tighten.
(NOTE: There is a right and left side caliper. The cal iper bleeder valve must be towards the top and facing the rear
of the vehicle to allow proper bleeding of the system).
STEP 17:
Install the new hose at the cal iper fi rst. Tighten, now attach to the metal brake l ine at the pan, tighten. Install the
cl ip into hose. securing it to the bracket. Once installed turn the steering right and left, lock to lock to ensure that
the new brake hose does not interfere with any moving parts and that the l ine is long enough to aacheive lock to
lock turns.
STEP 1 8:
You are now ready to repeat this procedure on the passenger side. Once completed you will be ready to bleed the system.
STEP 19: To bleed the complete hydraulic system. Fi ll the brake fl uid reservoi r with fresh dot 3 d isc brake fluid.
STEP 20:
Start at the master cylinder loosening each metal brake l ine to bleed air there fi rst, recheck the fl uid level.
STEP 21 :
Bleed the passenger side ca l iper si de cal i per first and then driver's side, remembering to not allow the reservoi r to
run dry!
STEP 22:
Do the fi nal system bleed. Start with the passenger side rear then driver side rear. Move to the front and bleed the
passenger side front, and finally the driver front. Do the final fi ll of the brake fluid.
STEP 23:
Rinse any spilled brake fluid off with water (brake fluid is water-soluble), be careful not t o let brake fl uid get on any
painted surfaces.
STEP 24:
Re-i nstall the front ti res and wheels, remove from the jack stands and lower the vehicle to the ground. Give the l ug
nuts a final tightening.
When test driving, be sure to ma ke a few slow short stops first to familiarize you rself with the vehicles new bra king
power and making sure that everything is functioning properly.
