Powerbuilt Disk Brake Cylinder Hone 3/4 Inch to 2-1/4 Inch, 3 Piece 1-1/8 Inch Lenght #220 Medium Grit Stones Included, Adjustable Tension - 648401

I bought this hone to fix one of my Maglite flashlights that suffered the results of a leaky battery. I keep a three cell Maglite in each of my two vehicles and have added the LED bulb to them for increased illumination. I'm beginning to lose faith in many battery manufacturers because they all seem to leak any more. Any attempt to be compensated for a new flashlight due to their faulty product is usually met with a "too bad, we can replace the batteries but that's it." I caught this in time so that minimal damage was done but pitted the interior of the tube. I'd thought about using a hone before but never did so this time I decided it was time to do just that. I wiped out the inside to remove any residue then put the hone in my drill and worked it in and out until I felt good about the job. There is still some pitting but for the most part, the light has been restored to a usable condition. In other words, it works! I have run across other things that I would have liked having this hone to smooth out the interior of a tube before so now I have one. I have another flashlight that I want to use it on but I hope I don't have to use it on any more of my Maglites. I'm sure that this hone will work if I have to work over any cylinders on engines too but I hate working on that sort of thing so maybe not. Otherwise, I found this to be a very durable and useful tool.

works as expected

I used this for a Ford V8 engine. I plan on installing simple cast iron rings, which require a rougher grit honing. This tool is perfect for that. If you are planning to install moly rings, this is not the tool for you. You will need something finer grit. Word of caution... you have to be very careful not to stick it too far into the engine or it will come out into the block where the stones will hit the engine casting and chip or break. They are easy to chip or break this way. Just be sure to get a good feel for the depth, speed, etc. and it will work great. Anyhow, the tool is pretty sturdy. It works like it should. After a short test run I found the right settings to get a perfect 30 degree cross-hatch on my engine cylinder bores.

Great Quality, Great Buy

With the introduction of the electric brake and limited replacement caliper supply, this tool is a life savor. The caliper piston on this system is electric and hydraulic operated. As a result, the piston tends to bind. This tool allowed me to rebuild and reseal my rear brake calipers on a 2021 rav 4. First reline 40,000 miles. This system is a maintenance issue to consider. Rebuild kit has a o- ring piston bore seal and a boot seal. Having a seal install tool helped for the boot seal. This piston rotates for the electric parking brake . It must be off before you start. A jack screw is under the piston. Don’t compress the piston. Bleed it then rotate it to get new pad install clearance. if tight when rotating the piston you better reman the calipers. Most pistons have slots to aid in piston rotating. My car didn’t have slots. A rag in channel locks worked . God bless Toyota. I have the e brake controller. This only partially backed off the parking brake due to the dual system on this caliper. Hydraulic/ electric. , Good luck. Mine worked iout well. It’s a two grand reline if you need rear calipers.

Gently use ! They are easy to over do

Needed to hone a bushing that has an id slightly larger than 3/4 inch. The hone would not fit into the bushing. Might work ok in bores 1 inch or greater id. Mfg needs to modify description or redesign hone.

It did what I needed it for, but just barely. Needed to hone out the four 1" diameter U-joint sockets on a SxS driveshaft. I gave each hole a "4 count" at medium speed, and let me tell you, these stones wore down QUICK. I barely got the last hole honed before they were out of shape too much to get a flat grind. I did not use oil, but I'm thinking that may have helped .. but not sure.

Supplier shipped the larger size, whereas I had ordered smaller. Quality of larger unit looked good. But won't be ordering again due to concern over a repeat of the supplier error fiasco. Thank goodness amazon returns work well.

merci

yup its good, fits the Harley Brake caliper perfectly

Excellent buy. Worked perfectly. Definitely recommend.
