Powerbuilt Adjustable Cylinder Hone Deglazer 2 Inches To 7 Inches - 648439

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.

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.

The media could not be loaded. Unlike other hones that have cotter pins in them this one is riveted together which I prefer to the cotter pins that can scratch cylinder. The spring won't just come loose unlike other that will fly all to pieces. Only con to this hone is they could have made the pieces on the end a little wider so you could smoothly go from one side of cylinder to the other.

Used the tool to open up a bronze 7/8 id bushing .004. Use lots of oil and clean the stones frequently. The surface finish was a little rough in the bronze material but could be easliy polished.

I damaged the receiving hole for new u-joints in my axle an needed a fix. This item trued up the hole removing the rolled over damaged metal, worked perfectly. Be careful, removes material quickly, I counted 15 seconds per hole to true up the bore on my axle shaft. If you use it to true up a hole I'd suggest 15 seconds run time then check bore. If still not true, run another 15 seconds, on an on, till bore is dressed.

Use this to enlarge the thumb hole in my bowling ball. Worked great!Remember that this item screws together clockwise. If you run the drill counterclockwise the hone will quickly come unscrewed. This is not a fault of the product, it’s just a fact.

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.

Hasta el momento no e tenido problemas en comprar en amazon, solo las semillas de yukas o casaba como le llaman que pague por 7 piesas y solo me mandaron 2 y espero que no se repita en el fururo pero en los demas todo bien quiera DIOS que continuen asi.
