Lisle 10400 3-Stone Disc Brake Hone

Exact replacement parts you need to replace the magnets.

I used these cylinder hones to polish some hardened steel dies. Although the stones are somewhat soft and wear quickly they provided a very smooth finish. I found I could manipulate the stones in the dies to spread the wear pattern along the length of the stones. I would not hesitate to use these again for the same purpose.

While this is designed for honing brake cylinders, I used it for final finishing of the head tube of a steel bicycle frame. This is to install the headset and fork. Overkill for what I needed, which was to remove leftover bits of paint (and some metal bits, most likely), but it beats paying the ridiculous sum that Park Tool charges for their admittedly nice, but overkill, bicycle specific tool.The tool feels solid for what it is. It does not include instructions if I recall correctly, but the concept is rather easy to figure for those with some mechanical aptitude, especially if you are tinkering with your brake cylinders. There is a threaded portion that adjusts the width of the bones and it fits into a drill.Chucked it into my cordless drill (Bosch, which rules in my opinion), and made quick work of the head tube debris. I’m talking maybe a few minutes at most in total, quickly checking in between each 10-15 second spin up and down the head tube. Not polished in feel, but smooth enough (don’t want to thin the tube). A tip is to be careful around entering and exiting the head tube, bearing careful to not chip the paint. Considering the top and bottom edges of the head tube will most likely be covered up by the headset, minor chipping is probably not an issue, but I like a scratch free frame. At least until the shiny wears off the new toy.Also, for a new steel frame, be sure to apply frame protectant to the interior after honing. I went with Fluid-Film, which is lanolin based, adding a not so nice wool smell to your frame (it dissipates very slowly). Better than rust.For my rather limited use, it is highly recommended. I’m sure it would work fine for brake cylinders, given it is Lisle brand. I have few Lisle auto specific tools and have no complaints.

They did the job, but I feel the stones wore out prematurely. The stones cost nearly the price of the complete hone.

I bought this because I've had too many bad experiences with overseas wheel cylinders. You can barely trust even the most well-known suppliers nowadays. Specifically, I had 3 sets of wheel cylinders leak in 2 weeks on one car, the last set that leaked was the straw that broke the camels back and took the axle seals with it causing gear oil to leak all over a brand new set of shoes. In hindsight, I should have rebuilt the ones that were on the car. I took the wheel cylinders apart and found pieces of shot inside one of them.At any rate, I'm (slowly) rebuilding the brakes on a 69 F250 and started at the LR wheel, which I found was sticking when the truck got hot. The wheel cylinder was completely jammed. I had to soak the pistons in Aerokroil and force them out with a brass drift. One side of the wheel cylinder was so badly pitted it was beyond salvaging, but I washed it with soap & water and a stiff brush and proceeded to hone it for practice. Glad I haven't lost the touch. Started by cleaning and drying the cylinder, clamped it in aluminum jaws in a vice, lubed the stones and cylinder with clean brake fluid and went after it. The cylinder came out nearly perfect with a nice cross-hatch pattern like a fresh cylinder wall, except for the deep pits from where some water must have set for a long period. I trashed into the scrap pile, but had it not been for the pits, it would have been serviceable. I'm sure I'll get good use from this tool in the future.

This is a great hone for honing out Moen shower valves.I know a of people use emery cloth rolled up to clean the valve body.But that no where near compares to the results on the finish this hone produces...... Once honed and the valve kit goes in, that Moen shower valve will feel as easy as new to operate and the new kit will last much longer.Highly recommend for Moen or other shower valves when putting in new kits. Just the right size for the shower valves.

It has good smell.

This tool works as designed. I have read a number of complaints about these sort of hones, and every one I have ever purchased has worked perfectly. These tools are NOT boring machines, they are designed to break a glaze in a cylinder or clean up minor surface rust. Looks like far too many people think these things can replace a $15,000 boring machine, and expect them to remove .001 or more, (They are not designed to remove material!) or that the stones are not stones and by definition they are brittle. If you hit they or drop the tools, they will crack. I used this tool to clean up the bore in a 3/4 cylinder that would cost $700 to replace.It worked perfectly, for my purpose the stones were just a little bit coarse, (Very high pressure air compressor) but for an internal combustion engine the grit would be fine. Bore was .850 inch and it will go a little smaller.

Worked well for a pair of jeep WJ calipers. Simple little tool that saved me some money. I'll probably lose it before it wears out since I can't see rebuilding calipers more than about once a decade.

I've used lyle tools for years and this is a good quality hone.Arrived a day early too.
