Front brake
Step 1: Identify Front Disc Brake ComponentsFront
Wheel Drive
Brake Assembly
Most
front disc brake components include: brake rotor, brake pads, brake
caliper, caliper mount and brake flex hose. Brake service usual occurs
between 20,000 and 40,000 miles depending on driver habits, road
conditions and brake pad/ rotor materials used.
Step 2: Remove Brake Caliper to Replace PadsRemoving Brake Caliper Mounting Bolts
Locate
primary caliper mounting bolts; apply wrench pressure counter-clockwise
(When looking at the head of the bolt) to remove the bolts, upper and
lower. Make sure the bolt threads are in good shape and replace if
necessary.
Step 3: Remove Front Brake CaliperRemove Front Brake Caliper
After
removing the primary caliper mounting bolts lift the brake caliper off
of the rotor and then tie or secure to the side, being careful not to
bend or kink the brake caliper flex hose. Thoroughly inspect brake
caliper and brake hoses for leakage, cracks or chaffing and replace as
needed. Next remove the brake pads (If not mounted in the caliper) and
secondary caliper mounting bolts. Notice how great protective gloves
work, most technicians use them on the job today.
Step 4: Remove Brake PadsRemove Front Brake Pads
Once
the brake pads have been removed, make sure if there is anti rattle
hardware to transfer to the new brake pads. Some brake pad manufacturers
will include the proper lube (Caliper slides) and anti-rattle hardware
to ensure proper performance of their product.
Step 5: Remove Caliper MountRemove Caliper Mount Bracket
Finish
removing secondary caliper mount bolts and remove caliper mount. Note:
clean and lube caliper slides and pad friction surfaces of all foreign
material or build-up.
Step 6: Remove Brake RotorRemove Brake Rotor
With
the caliper mount out of the way you can now remove the brake rotor.
Sometimes it can get stuck so you may need to tap it with a hammer or
use penetrating oil to free it up. Some manufacturers use small screws
to hold the rotor on as well. Clean and inspect wheel studs, replace if
any are damaged. Also clean bearing hub rotor mount surface to ensure
the proper mounting of the new brake rotor. Inspect the ABS sensor wheel
for cracks or damage and replace as needed.
Step 7: Depressing the Brake CaliperResetting Brake Caliper
To install the new brake pads you must retract the brake caliper piston. Remove the
master cylinder lid or open the brake caliper bleeder screw to allow excess
brake fluid
to be released if necessary. Install C clamp tool and gently tighten
clamp until caliper piston is fully depressed. Note: use old brake pad
to protect the caliper piston. Close the bleeders once the piston is
retracted completely
Step 8: Installing New Brake RotorInstall Brake Rotor
Install
new brake rotor, the new rotor is manufactured with a protective film
over the rotor to keep it from rusting, remove protective film with
brake cleaner before installing; also after the brake job is complete
you may experience a small amount of smoke from the rotor when first
used. This is normal and will go away after the first couple of uses.
Step 9: Installing New Front Brake PadsInstalling New Brake Pads
Reinstall
the front brake caliper mount, and then install front brake pads. Make
sure the pads are seated properly in the caliper mount; it must be a
close fit to work properly..
Step 10: Reinstall Front Brake CaliperRe-Install front Bake Caliper
Reinstall
front brake caliper and reinstall caliper-mounting bolts, recheck all
mounts and mounting bolts. Check the caliper slides to be sure there is
no bind and that the caliper moves freely back and forth on the caliper
slides. Bleed brake system per manufacturer's specifications to relieve
any air trapped in the system. Before driving the vehicle, push the
brake pedal down and let it up slowly, repeat until normal brake pedal
operation resumes, this operation is forcing the brake pads to travel to
the brake rotors.
I'm not sure what the caliper housing looks like and I'm not seeing additional bolts other than the two I removed to take off the caliper that secures the pads? It's difficult to see behind the rotor . . . I was told by someone at the auto parts store that nothing should be holding the rotor on once I remove the caliper . . .
For anyone interested I finally resolved this problem with the rotor on my Chrysler Concorde. It took over 2 hours of pounding, pulling and leveraging under the rotor but it finally broke loose. I think it was simply a poorly tooled original part or it was no longer shaped correctly--that coupled with rust and corrosion made it seem like it was cemented on. The new part slid on and fit so much better. And the second rear wheel was a pice of cake as the old rotor slid right off just like they are supposed to. Everything is back together and works like a charm. I will say I'm a little disappointed in the lack of follow up help from FixYa. Thanks for the initial quick response though.
