Brake Rotor pulsing
Has anyone tried the Braketru on th car RotorResurfacer
at braketru.com
They are to be glued to your old pads, run car ( on jackstands) press brake 3-5 seconds and done, new pads and go.

 

I saw that on TV. I'm not sure how good it will work. I wouldn't try it on my car though...

 

Its an unnecessary gimick, I think.

 

I hope you're not serious. I know it's tough to replace rotors on those cars, but that thing's a gimmick. (and a half)

 

I would not trust such a thing to do a good job. There is no way to tell how much (or little) it will cut before you use it. So if you cut the rotor too thin, it is prone to breakage.

You have to understand, resufacing the rotor is not something you need to do that often. Resurfacing is something shops do alot because it is cheap and makes money. It only needs to be resurfaced if it is deeply scored or is out of parallel. You can get a far worse surface after a slow cut than a slightly worn rotor.

This thing is just a gimmick. I can imagine sandpaper can do the same thing for a much lower price.

 

a new rotor is usually cheaper than resurfacing anyway. Autozone blanks go for about 20 bucks a pop, and brembo blanks are about 30. If you really have rotor issues, I would just buy new ones

 

What I was thinking was that abrasive that "cuts" the rotor could get embedded into the pad itself and it will wear grooves and chew up a rotor...

 

Don't bother with the resurfacer. Have you ever seen the mechanic use a brake lathe? It requires some pretty fine and accurate cuts and can only be done on the same rotor about 2 times.

If you want to save some money, buy some new high quality rotors and pads at http://www.partspalace.com.

wow, when I was getting new rotors for my 95 EX AutoZone told me there blank rotors were 50 each, front and rear. I got Brembo blanks from Colletti for 27 each, front only. Got rears somewhere else for like 22 each, don't know how much they are from Colletti.

 

Thanks for the advise, I have always had the same experience with other cars, that is rotors don't always need to be replaced. This car '97 Accord LX i4 is not typical though. I have 106K miles on it, 90% highway, the orginal tires still had much tread left on them @ 102K but I had developed a pedal pulsing on braking which started when I had the pads replaced @ about 80K. They were worn out but never touched the disk and so only the pads were replaced w/ Hondo pads. You can tell I don't drive the car hard because of the unusual mileage I got from the tires and brakes! The tires were replaced not because they were worn, but rather because I had checked the rotors for thickness and run-out, both micrometer thickness and dial indicator run-out were within original specifcation. Now I am back to suspecting the rotors, but they are not worn or grooved, changing disks appears to be a large job on these cars, calls for dismantling tie rods, removing bearings with press, unbolting steering knuckle and finely removing disks. New disks get new? bearing pressed in, reassembled and freshen alignment. All for the rotors. Seems a poor design to me. That's why I want comments from someone who had actually used the BrakeTru and what their experience has been.
Thanks, I appreciate you comments.

The abbrasive is applied to your old pads, which are tossed afterward. Rotors need to be cleaned w/ Brakekleen but that's all.
