Jekit Racing 4 Piston Red Caliper 330x28mm Big Brake Caliper System
Our Caliper has a range of Standard 4 Piston road car
calipers to suit lightweight mainly front but rear applications
also.
All performance road brake calipers use conventional seals in
conjunction with a dirt seal and are finished with a black PTFE
paint coating which is impervious to normal brake fluids & high
brake temperatures, with the custom logo highlighted in yellow, or
a gloss red paint finish, and the custom logo highlighted in
white.
The Standard 4 Piston Caliper Range consists of the following below:
CP5200/CP9200/CP5040/CP7600/CP7609/CP8530/F50/GT4 and son on.
You can choose the caliper type which you prefer
Removal Brake kit
Put on your safety glasses.
Use a breaker bar to loosen the wheel lug nuts. Do not remove the
nuts completely at this time.
Safely raise and support the vehicle using a jack and jack stands.
Chock the rear wheels and set the parking brake.
Remove the lug nuts by hand. Then remove the wheel and tire
assembly.
Place a fluid catch pan under the caliper.
Warning: Brake fluid is corrosive. Keep it away from your car’s
finish.
Unbolt the brake line from the caliper. Set the banjo bolt and
sealing washers aside.
Plug the brake line using a brake hose plug. This is done to
prevent brake fluid from leaking out during repair. If you lose
enough brake fluid, the master cylinder will go empty, making the
brakes more difficult to bleed.
Remove the caliper mounting bolts.
Remove the caliper by pulling it up and away from the rotor. If the
caliper is stubborn, you may need to use a large screwdriver or pry
bar to help remove it.
Remove the brake pads from the caliper (this is only necessary for
fixed calipers).
Installation
Prepare the new caliper for installation by following the
instructions included in the box.
Most new calipers come with the piston fully seated in its bore.
But if yours does not, you’ll need to push the caliper back in its
bore using a C-clamp or disc brake spreader. When doing this, keep
an eye on the master cylinder to ensure fluid doesn’t get pushed
out of the reservoir.
Install the brake pads into the brake caliper (this is only
necessary for fixed calipers).
Position the new caliper over the rotor.
Tighten down the caliper mounting bolts and use a torque wrench to
tighten them to your vehicle manufacturer’s specifications.
Remove the brake line plug.
Reinstall the brake line with the banjo bolt and new sealing
washers (replacement calipers usually come with new washers). Use a
torque wrench to tighten the banjo bolt to your vehicle
manufacturer’s specifications.
Refill the master cylinder as needed.
Bleed the brakes either manually with an assistant or with a
special tool (pressure bleeder or vacuum bleeder).
You need to bleed all four brakes, not just the one you serviced.
The procedure usually starts at the brake caliper or wheel cylinder
(if you’ve got rear drum brakes) farthest from the master cylinder.
Typically, the sequence is as follows: right rear, left rear, right
front, left front.
To bleed your brakes with a buddy:
Ensure that the master cylinder is full of fluid.
Attach a rubber hose to the end of the bleeder screw and make sure
the hose fits snugly over the screw’s nipple. Submerge the other
end of the hose in a clear container (such as an old water bottle)
partially filled with brake fluid.
With the engine off, have an assistant depress the brake pedal then
hold it to the floor. Instruct your friend to tell you when they
are holding the pedal down.
Using a line wrench, crack the bleeder screw open but do not remove
it. Tell your assistant that you have the bleeder open.
Allow fluid to run from the bleeder screw into the container. Watch
for air bubbles entering the container.
When fluid stops flowing, close the bleeder and tell your assistant
that it’s closed. Your assistant can now release the brake pedal.
Note: You’ll want to keep an eye on the master cylinder fluid level
during this procedure. Air will get sucked back into the system if
the master cylinder runs out of fluid.
Repeat the procedure until no more air is seen coming from the
bleeder.
Move to the next corner of the vehicle and repeat the bleeding
procedure until you’ve covered all four wheels.
Once the entire system has been bled, check brake pedal feel. It
should be firm. If not, continue to bleed the brakes until pedal
feel is satisfactory.
Reinstall the wheel/tire assembly onto the lug nuts.
Tighten the lug nuts until they’re snug using a ratchet and socket.
Safely remove the jack stands and lower the vehicle.
Use a torque wrench to tighten the lug nuts to your vehicle manufacturer’s specifications.
Before driving the vehicle or putting it in gear, pump the brakes several times to ensure they feel firm. DO NOT drive the car until the brakes feel solid.
Brake Caliper Replacement Tips
If you have a bad brake caliper, don’t bother trying to rebuild it.
Most replacement calipers are cheap enough that rebuilding isn’t
worth the hassle. You don’t want to mess with your brakes, so be
sure to get a quality new or remanufactured caliper from a
reputable manufacturer.
One last tip: Check the condition of your brake pads and rotors. If they’re worn, now’s the time to replace them. Same goes for your brake hoses.
