Caliper Rebuilding

Centric Parts has gone to great lengths to maintain its advantage above the competition by utilizing the latest machinery, processes and Centric custom built testing equipment. Centric Parts is the industry leader in remanufactured brake calipers.

After each caliper core is inspected and identified, it is disassembled. All rubber seals, boots and hardware are discarded. Each reusable component is inspected, cleaned and refinished to ensure maximum life.

After tear-down each caliper core is heated to over 500 degrees. This process burns off any residual oils, grease or brake fluid leaving a clean caliper body.

Parts are then tumble blasted with steel shot to further clean any rust or scale left on the calipers. Parts leave the shot blaster as clean as a new part from the foundry.

After shot blasting, all calipers are treated with an anti-corrosion finish. This aqueous based solution prevents rust and preserves shelf life.

Each caliper is thoroughly inspected before being sent for reassembly.

Every threaded port or bleeder hole has the threads chased to eliminate cross threading during installation. This process also ensures leak free performance for the life of the caliper.

All bores are brushed and cleaned to ensure proper fitment and performance of the new boot and seal.

The piston, boot and seal are installed using appropriate lubricant and is done according to original manufacturing specifications.

After assembly EVERY CALIPER is tested on Centric’s custom designed pressure tester. No caliper gets packaged without first getting the green light from Centric testing equipment. This ensures that Centric Calipers will work to original specifications right out of the box.

After receiving the green light from Centric testing equipment all caliper identities are confirmed. Then they are boxed, labeled and shipped.

PREMIUM BRAKE ROTORS

Centric Premium black rotors feature Original Equipment specifications and production processes. These Centric rotors are manufactured to meet QS and ISO Quality System Standards. Centric premium rotors utilize an Electrocoating finish that provides long lasting corrosion protection. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. Phosphate finishes utilized by other manufacturers provide only minimal protection from the elements; these finishes are generally only effective for the shipping and storage portion of a rotor’s life. The addition of heat and moisture eliminates the effectiveness of phosphate finishes resulting in immediate corrosion once installed in the vehicle.

Centric Parts also offers 125 Series High Carbon Brake Rotors for certain vehicle applications. High Carbon Rotors feature advanced metallurgy that greatly reduces the possibility of pad squeal especially with higher friction, European style brake pad compounds. Proprietary Molybdenum and Chromium alloys resist cracking in high heat situations and increase friction couple for improved braking power and stopping performance.

Double Disc Ground

Centric premium rotors feature a double disc ground, taper free finish. Double disc grinding ensures parallelism, eliminates run out and provides near perfect disc thickness variation (DTV). Double disc grinding leaves a non-directional finish on the friction surface area for more effective pad-rotor break in. This special finish also provides quieter and smoother stops. The surface Roughness production standard for Centric Premium Brake Rotors: RMS=64.3 or Ra=1.6 micro-meters (63 micro-inches).

Machined Finishes

Centric premium rotors feature 100% fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component. In addition, Centric Premium rotors are inspected for balance and mill-corrected to a tolerance of less than 2oz.inch.

E-COATING

Even though E-coat has been with us since the 1930's, it is mainly due to interest and capitol investment in the 1970's by the automobile industry for primers that made it popular. Since then, the technology has found its way into more decorative and functional (non primer) single coat application like CLEARCLAD.

Timeline:

• 1940's: Experimentation into electrodepositing phenolic resin coatings onto electrical wire on a continuous basis.
• 1950's Full scale development of electrodeposition of anti-corrosive paint primers on automotive bodies.
• 1960's Development of exterior durable, light colored electropaint resin systems suitable for domestic appliances, architectural aluminum etc. (Principle technology so far -anodic)
• 1970's Cathodic technology displaces anodic as the principle system in the automobile industry. Such systems are adapted for small scale use in the electroplating industry (circa 1978).
• 1980's Technology continues to evolve as protective coatings for the metal finishing industry

Process Mechanism:

E-coat is an emulsion of organic resins and de-ionized water which is in a stable condition. The E-coat solution also comprises of solvents and some ionic components. When a DC voltage is applied across two immersed electrodes the passage of current is accompanied by electrolysis of water. This results in oxygen gas being liberated at the anode (positive electrode) and hydrogen gas liberated at the cathode (negative electrode). The liberation of these gases disturbs the hydrogen ion equilibrium in the water immediately surrounding the electrodes. This results in a corresponding pH change and this in turn de-stabilizes the paint components of the solution and they coagulate onto the appropriate electrode.

• Cathodics electropaints are stable except at high (alkaline) pH. Anodics are stable except at low (acid) pH.
• Electrolysis of water causes the cathode to become alkaline and the anode to become acid.

Electrophoresis is a well documented process whereby electrically charged particles in a conductive medium will migrate to the electrode bearing the opposite charge under the influence of DC voltage. Although many technical descriptions of electropaint ascribe electrophoresis to the deposition process it is not the predominant mechanism. However it is very common to refer to eletropaint as "Electrophoretic".

Application:

An unfinished product is immersed in a bath containing the electrophoretic paint emulsion and then an electric current is passed through both the product and the emulsion. The paint particles that are in contact with the product adhere to the surface as described in the above mechanism and build up an electrically insulating layer. This layer prevents any further electrical current passing through resulting in a perfectly level coating even in the recessed parts of complex shaped objects. The product is then removed from the paint bath and baked in an oven. Due to the insulating nature of the deposit as described above, it is possible to accurately control the thickness over the part. Whereas with plating and anodizing thickness is controlled by amp/time relationship.

With E-coat, the thickness is controlled by voltage. The time is not as critical as once the part is coated and insulated no more coating will take place. Depending on surface area and complexity of the parts, most coating is accomplished within 2 minutes. this highlights one of the big equipment differences. Plating and anodizing require low voltage and high amperage rectification. E-coat requires high voltage and low amperage (1sq. ft. draws 1.5 amps max) rectification.

Electrocoating is a method of painting which uses electrical current to deposit the paint. The process works on the principal of "opposites attract". An E-coat system applies a DC charge to a metal part immersed in a bath of oppositely charged paint particles. The paint particles are drawn to the metal part and the paint is deposited on the part, forming an even, continuous film over every surface until the coating reaches the desired thickness.

The electrocoat process can be divided into four distinct steps:

• 1. Pretreatment cleaning and phosphating cycle.
• 2. Electrocoat bath cycle.
• 3. Post rinse cycle.
• 4. Baking and curing cycle.

Electrocoating Advantages:

• 1. Uniform coating thickness over all areas including sharp corners, recesses and areas that would be hard to reach with spray painting.
• 2. Electrocoating is automatic and labor saving, requiring little maintenance.
• 3. Electrocoating saves the costs and operating expenses of air supply systems, fire protection equipment, respiratory hazards and costly cleanup. The paint material is water based and non-toxic.
• 4. Approximately 95% utilization of paint with no overspray, drip or drain losses.
• 5. Complete paint coverage -no touchup required.
• 6. parts may be racked on the conveyor, one on top of the other with no concern for dripping.
• 7. Primers applied by electrocoating come out smooth and may be top coated without sanding.

Electrocoat Details:

The system offers better uniformity, higher density and less permeable coating than spray applications, saving up to 50% on coating materials. It is environmentally friendly, reducing emissions up to 70% and achieving nearly 100% coating utilization. Electrocoating also eliminates expenses associated with overspray cleanup and disposal.

Dial Your Coating:

he main factors controlling film thickness are the applied voltage and the film resistance. Increasing the coating voltage or lowering the specific film resistance causes an increase in film thickness. You simply dial in the desired coating thickness. The electroplating process will continue until the organic film deposited provides an electrical insulating resistance which prevents further current flow. When the coated parts are removed from the bath, they are rinsed in permeate and deionized water to remove non-deposited paint particles.
