A rural farm shop outside Waukee called us last year needing a 2 post car lift installed to handle brake service and rotor swaps on everything from pickups to the occasional grain truck axle work. The owner had already bought a used lift off a classified ad and just wanted it hung and running by the weekend. We walked the bay, looked at the lift, and found cable wear that would have made it unsafe within months. That job turned into a checklist we now walk every farm shop customer through before money changes hands, and we’re sharing it here so you don’t learn it the hard way.
Find the correct cable set for your lift model before install day. We stock cables for Rotary, BendPak, and Challenger two post lifts and can match them by serial number.
Why Brake Work Puts More Stress on Cables Than Oil Changes
Brake and rotor service is harder on a two post lift than routine oil changes because the vehicle often sits at full height for extended periods while a tech pulls wheels, inspects rotors, and works calipers. That sustained load time, repeated multiple times a day in a busy farm shop handling trucks and trailers, puts more cumulative stress on the cable system than quick in-and-out oil change work. If you’re planning a 2 post car lift installed specifically for brake service, the cable inspection step before purchase matters more than it would for a lighter-duty bay.
We see this constantly in rural Iowa shops that do their own mechanical work on farm trucks, trailers, and personal vehicles. The lift gets loaded heavier and held there longer, and a used lift that looks fine sitting empty can reveal frayed strands or uneven cable tension the moment it’s loaded and held at height. That’s exactly the kind of defect that doesn’t show up in a five-minute walkaround.
The Pre-Purchase Checklist: What to Check Before You Buy Used
Before you commit to a used lift for brake and rotor work, run through this list. First, ask for the model and serial number and confirm it’s a brand we can still source cables and arm parts for — Rotary and Challenger units are generally the easiest to keep serviceable long-term. Second, ask how the lift was used previously; a lift that spent its life in a light-duty oil change bay has less cable wear than one that spent years lifting heavy trucks for brake and suspension work.
Third, physically inspect the cables if you can see the unit before it’s disassembled for transport — look for rust, kinks, flat spots, or any strand separation. Fourth, ask about the anchor bolts and baseplate; if the seller doesn’t know the concrete thickness where it was installed, as we’ve run into on farm shop calls before, that’s a red flag about how carefully the lift was maintained overall. Fifth, get a firm answer on whether oil and hydraulic fluid are included, since an empty system adds cost and time to your install day. A 2 post car lift installed correctly the first time saves you from redoing this whole process in a year.
Cable Inspection Intervals Once It’s Running
Once your lift is installed, cable inspection isn’t a one-time event. For a farm shop doing regular brake and rotor work, we recommend a visual cable check every thirty days and a more thorough inspection — checking tension equalization between the two columns, looking for wire strand damage, and confirming the safety latches engage properly — every six months. Heavier, more frequent loading from brake work means cables show wear faster than in a lighter-use shop.
Most manufacturers recommend cable replacement somewhere between five and ten years under normal use, but a rural shop pulling truck wheels and rotors daily should plan on the earlier end of that window. We tell every customer near Waukee the same thing: don’t wait for a cable to visibly fray before replacing it. The moment tension looks uneven between the two sides of the lift, or you hear any new noise when raising a loaded vehicle, that’s your signal to swap cables immediately, not next month.
New vs Used: What Changes About the Install Itself
Getting a 2 post car lift installed new versus used changes more than just the price tag. A new lift comes with fresh cables, current safety latch designs, and a warranty that covers early failures. A used lift, even a good one, is an unknown quantity until our crew gets hands on it — which is exactly why we inspect cables, arms, and hydraulic lines as a standard part of every used-lift install we do in the Waukee area.
We’ve installed both, and we’re not going to tell you every farm shop needs to buy new. A well-maintained used Rotary or Challenger lift with documented service history can be a smart purchase. But if you can’t get that history, budget for a full cable and hardware inspection as part of your install cost, not as an afterthought. It’s a lot cheaper to replace a questionable cable during install week than after it’s holding up a loaded truck with a tech underneath.
Concrete and Anchoring: The Part People Forget to Ask About
Cables get all the attention, but the anchoring underneath your 2 post car lift installed in a farm shop matters just as much for long-term safety. Older ag buildings often have concrete poured for equipment storage, not for the point-loading a two post lift puts on four small anchor bolt patterns. We measure slab thickness and check for rebar interference on every install, because a lift can have perfect cables and still be unsafe if the anchors are set in undersized concrete.
If you’re shopping for a used lift and the seller can’t tell you what the concrete thickness was at the original install site, treat that the same way you’d treat unknown cable history — as a gap you need to close before moving forward. We’ve had to pour supplemental concrete pads for farm shops near Waukee more than once because the existing slab couldn’t safely anchor a lift rated for real brake and rotor work on trucks.
What a Proper Install Day Looks Like
On install day for brake-service-focused shops, our crew checks concrete thickness and rebar depth first, confirms the bay has clearance for full-height lifts with a loaded truck axle up, and only then moves to setting columns, running cables, and calibrating the safety latch system. We test the lift at full load simulation before we call the job done, checking cable tension equalization side to side.
For farm shop owners near Waukee, we also walk through a simple maintenance routine before we leave — what to check monthly, what to check every six months, and when to call us for a cable or arm inspection rather than guessing. A 2 post car lift installed by a crew that also teaches you the maintenance schedule is worth more than the cheapest quote you can find, because the lift you’re trusting with your safety during brake work needs to actually stay safe for the next fifteen years.
