Review on 🔧 Effortless Brake Piston Removal with OTC 4799 Locking Pliers - A Must-Have Automotive Tool! by Daniel Jackson

I need to disassemble my TOKICO calipers. Using air or lubrication was not a viable option. (Once a piston comes out, the pressure disappears and no more pistons are removed). This tool looked pretty good. The grooved tabs on the ends of the inverted vise-style tool seemed like an epic idea. The problem was/was that the tool wasn't strong enough to do the job. You can pinch the pistons internally and possibly make them spin, but any pressure in the linear direction (towards the caliper/piston bore) will cause the tool to slip. The teeth on the knurled lips are not deep enough nor "aggressive" enough to hold the pistons. You can tighten the handles until you need 4 hands to squeeze them together, but as soon as you start twisting and pulling, they immediately disengage from the pistons. I finished all 12 pistons after a few hours of struggling, swearing, and sweating. , via this port clamp. Lube, time, swearing and sweating seems to be the key to getting the piston out. The oven method might work, but honestly, who has time to bake a caliper 12 times to get all the pistons out? fighting them, swearing and praying takes about the same amount of time and is actually more therapeutic. I have a feeling that channel blocking, vise, or someone still making a quality instrument could take this idea and come up with something more usable. If your pistons are clean, seals and fluid are fresh, and your bike is maybe a year old, they'll probably run just fine. For the real world it's time to fix those brakes because they're all fed up and not being applied/released, then this tool will try every bit of your resolve and patience.
