Now a word about torque, the twisting force that tightens a bolt.īecause caliper bolts MUST stay on, they need a LOT of torque. They’re often called “caliper bracket bolts” because they attach to the part of your caliper called the bracket, and hold it tight to the spindle or steering knuckle. What we are talking about are what you see above - the bolts which hold calipers onto your car or truck. Nor are we talking about bleeder valves, bleed screws, banjo bolts or anything that holds on brake lines or lets you bleed the brakes.(These bolts get stuck too, but that’s another problem.) We’re not talking about caliper pin bolts, or lock bolts, which hold guide pins in place on a floating caliper.(This is strictly a disc brake conversation.) We’re not talking about bolts on drum brakes.What Caliper Mounting Bolts Are and Aren’t…įirst, a word about what we’re not talking about… And it’s not just calipers and rotors and pads, but the nuts and bolts - the hardware holding things in place. Your brakes are a system that is put under enormous pressure and over months and years. It was my introduction to “caliper mounting bolt stuck.”įor this reason - stuck caliper bolts - Carlson recommends replacing them anytime you replace your calipers. That led to me trying to remove my calipers and, eventually, heading to see Dave, the mechanic at the Sunoco station a block away. And when I looked, I saw fluid at the base of my right front wheel. I wasn’t sure, but in the turmoil, I thought I’d heard them squeak. But the next day I decided to look at my brakes. He ran around the front of my car yelling and slammed his hands down on my hood.Īs it turned out, his dog (and my hood) were fine. I looked and saw a large man running towards me from his driveway. I hit the brakes and, a moment later, heard a scream to my right. Here’s a link to the Carlson sales support page, if you need to order new bolts.Ī few years ago, I was driving down a neighborhood street near my home, when a dog darted in front of my car. Stuck or frozen caliper bolts are one of the problems that come from reusing old parts during a brake job. Which means having a stuck caliper bolt is something bugging lots of people. People googled those phrases, and similar ones, over 10,000 times last year. What would you be doing in the situation? I have my local shop on call as a absolute worst case scenario.“Brake caliper bolt stuck” and “caliper mounting bolt stuck” aren’t phrases people say, but thanks to Google they’re likely why you’re reading this. I’m willing to buy an extractor set and drill bits and go to town, If that’s the best possible solution for this issue. So what I’m asking is what would be the best possible attack on this without damaging any threads or the caliper bracket or anything like that? So as I stand now, I can’t get the rotor or caliper bracket off to replace the parking brake hardware and shoes because I can’t get the caliper bracket bolt out to remove the caliper and the bracket So far so good but the last bolt of the job, a 14 mm caliper bracket bolt snapped as I was tightening it down … I could only think because I was getting tired and I decided to put a extension pipe on the tool and it gave me way too much leverage. I was going to work in steps, do all the brakes first then re-attack the rear parking brakes a day or two later. Long story short I upgraded the brakes rotors pads and was going to replace all the hardware/shoes in the parking brake system.
