Ask anyone what a “complete” brake job is and you’re likely to get a variety of answers. In the context of professional automotive repair, I define complete as meaning correctly done.
Why? Because the actual work that needs done to any given vehicle can vary depending on vehicle mileage, age and condition. And it can vary based on the equipment. For example, do you have access to a brake lathe? As a counter professional, you’ll have to dig into the details with your customer to determine what they need. However, there are simple guidelines to follow that will ensure you’re advising a “complete” brake job every time.
Brake Fluid, Brake Fluid, Brake Fluid
Above all, clean brake fluid is my first requirement.
It’s probably one of the most overlooked vehicle services, and most people don’t think of it as part of a brake job. It’s an afterthought only considered if they’re forced to do it. Anytime I perform brake work, the first part of the inspection is the bleeder screws. They must be able to open. No brake job is complete without flushing the brake fluid.
There’s no need to get “crazy” with it either when it’s done on a regular basis. A couple small 12-ounce bottles are plenty. Use a clean suction-bulb to remove as much brake fluid as you can from the master-cylinder reservoir, refill it, then flush fluid through until you can fit the contents of both bottles into the reservoir. Start with five strokes at each wheel until you see how much fluid is being forced through, so you equally balance the flushing from front to rear.
Contaminated brake fluid is corrosive and damaging to all the internal brake-system components, and it can cause poor braking performance. Even though every manufacturer specifies to flush it on a regular basis, it’s still out-of-sight, out-of-mind for a lot of people. In my opinion, you can’t change the brake fluid too often.
A complete brake job not only includes fluid, but also calipers or wheel cylinders in any situation where the bleeders don’t open.
Pads and Rotors
When disc brakes are being serviced, pads and rotors are at the core of the job. It’s far less common to resurface rotors than it has been in past times, and it doesn’t matter if you take that road or go with new. But the bottom line is something must happen with the rotors. “Slapping” a set of pads on old rotors is an immediate fail. The pads will never bed in properly, and you’ll only be faced with poor brake performance, uneven pad wear and unwanted noise.
The bottom line: Rotors must be resurfaced or replaced for the job to be complete. By the same token, old pads on new rotors equals an incomplete brake job.
Why would someone do this? Your guess could be as good as mine, but believe me, I’ve seen it all and I’m sure you have too. New pads and rotors bed in together. In other words, they rely on each other for proper brake operation.
Drum Brakes
If you thought there were some offenders with disc brakes, drums are often worse. For some reason there seems to be a perception that brake drums miraculously never need service, but the same theories hold true. If you’re replacing brake shoes, the job is only correctly done by resurfacing or replacing the drums.
Hardware
Hardware is anything from springs and hold-downs on drum brakes to anti-rattle clips and slide-pin boots on disc brakes. All these little pieces are important to proper brake operation. On drum brakes, even though everything may be intact, it’s also old and the springs will simply be fatigued. On disc brakes, the same holds true and even anti-rattle clips that look OK can be worn or fatigued in some manner. Luckily, most pads come with the hardware. They don’t put it in the box just for fun.
One of the most overlooked parts of disc-brake service is the fact that the pads must be able to move freely in the caliper bracket and the calipers also must be able to move freely back and forth. Most calipers (excluding fixed calipers) feature slide pins that allow this to happen. No brake job is complete without removing the slide pins, cleaning them up, lubricating them and reinstalling them with new boots when required.
It’s surprising how often the slide pins are stuck and how often brake pads are jammed in place due to rust, and the rust must be completely removed to allow free movement of the new brake pads. Stuck pins or stuck pads cause uneven and accelerated wear, dragging brakes, pulling and excessive heat buildup.
Lubrication
I touched on it already, but it’s worth a second mention. In addition to the slide pins on calipers, the brake pads require lubrication any place they contact the caliper bracket or caliper. Brake lube is specifically formulated to a) not damage or swell rubber components such as piston or slide-pin boots, b) prevent vibrations that cause noise, c) lubricate the pad contact points so they move freely in the caliper bracket and d) resist washing out.
In the case of drum brakes, the backing plates feature specific contact points for the brake shoes, which should be cleaned and lubricated. Brake shoes also require lubrication at pivot and contact points between the shoes and hardware.
Inspection
Determining what is required for a complete brake job can only be done through inspection and disassembly. It’s easy to see worn-out pads and rusty rotors through a wheel, but even when that’s evident, you can’t see anything else until you take things apart. This is when you inspect for brake-fluid leaks, seized or damaged hardware, torn dust boots and functional bleeder screws.
If leaks are found or dust boots are torn on a caliper piston or wheel cylinder, or if the bleeder won’t open, the components need to be replaced. Only until disassembly is performed during an inspection can you say absolutely what’s needed for any given vehicle. Sure, we can all look at a 50,000-mile four-year-old vehicle and say that it needs pads and rotors, and most likely those are the only hard parts it will need. But it’s no guarantee, and the higher the mileage and older the vehicle, the more likely we’ll find something else, which leads to the next category …
Recommending Parts
There’s always a way to work into the conversation of a complete brake job. The next time someone comes in and wants pads and rotors, you might ask, “Would you like me to look up caliper availability just in case a bleeder screw doesn’t open, or a caliper pin is seized?” If they’re an experienced technician, they know how often that happens, and they’ll likely say yes, just to know in case they need them, and they’ll appreciate it!
If they’re new at all this, it will get them thinking and open the door for your advice. The next thing you know, they might change their mind and decide to buy new calipers – or at minimum they’ll leave with the extra goodies they need for a complete brake job, such as brake lubricant, brake fluid, brake cleaner and some shop rags. If they get into the job and realize there’s a problem, they’ll be right back at your store.

KYB recently unveiled the KYB Parts Catalog app.
While most mobile catalog apps only ask for the year, make and model when searching for part numbers, KYB said its app dives much deeper, requesting information such as engine size, trim package and drivetrain type when applicable.
The additional levels of detail provide “an accurate and much narrower list of recommended shock-and-strut applications and part numbers,” according to the company.
With the app, service writers and technicians can quickly search for the part they need without accessing a computer. The app also provides recommended part numbers for performance-upgrade shocks and struts, strut mounts, boots and bumpers if available.
The app can recommend the closest retailer or wholesaler from which to order the part, KYB noted.
“The new KYB Parts Catalog app quickly provides repair shops with the right part number, helping to reduce repair time and opening repair bays quicker,” the company said in a news release.
Those who were using the KYB Shocks app will be automatically updated to this latest version, KYB said. New users can download the KYB Parts Catalog on The App Store and Google Play.

KYB said it has developed an environmentally friendly hydraulic fluid for shock absorbers.
The newly developed SustainaLubeliminates the environmental risks associated with petroleum, according to KYB. The
Full release to the market is planned for 2026.
The new fluid contributes to carbon neutrality by switching from petroleum-derived base oil to naturally derived base oil. It absorbs CO2 from the atmosphere during cultivation of the plants used for the base-oil raw materials, also reducing CO2 emissions during transportation, according to KYB.
SustainaLub is biodegradable up to 60% or more according to the Eco Mark certification standard (OECD301). The base-oil and additive formulation is recyclable, reducing environmental issues in the long term, KYB noted.
“As a specialized global manufacturer of hydraulic equipment, KYB has long been involved in maintaining and improving the safety and comfort of automobiles,” the company said in a news release. “Using that experience, we are striving to achieve environmental balance without compromising performance or reliability. Not only does SustainaLub improve maneuverability and stability by applying it to the various damping force valves that we already offer, but it also improves the feel of the product by applying friction-control technology, for example KYB Prosmooth shock absorbers.”
Replacing petroleum-based oil in KYB shock absorbers with this new hydraulic fluid will save up to 15.6 million liters of oil per year, according to KYB.
Tested in Japan
All new KYB products undergo reliability evaluation at the KYB Development Center in Japan.
“Thorough performance and quality evaluation involves both bench tests and actual vehicle testing on our state-of-the-art test track,” KYB said. “This in-house design of a hydraulic oil recipe is unique to a manufacturer specializing in shock absorbers.”
The KYB team participating in the All Japan Rally Championship JN-2 class introduced SustainaLub to their vehicles from Round 6 onwards They analyzed and verified the performance and durability in the harsh race environment, KYB noted.
In addition, SustainaLub was trialed in the vehicle used in the Lexus ROV (Recreational off-Highway Vehicle) Concept customer-experience program. It was used for Lexus’s first ROV equipped with a hydrogen engine. The data accumulated also contributes to technology development for future practical applications, and work toward the realization of a carbon-neutral society.
“KYB plans to ultimately apply the technology to all hydraulic products involved in realizing a sustainable mobility society,” the company said. “As a specialized manufacturer of hydraulic equipment, KYB has long been working to improve the ride comfort and handling stability of automobiles. Based on this experience, KYB will continue to pursue advances in performance and reliability while keeping environmental impact at the forefront of development.”
