How to get brake rotors straight?

[Hog_]

 

But as Big H would comment. Maybe it was their choice not be straight in the first place.

 

Okay' date=' I'm ducking so long.

DISCLAIMER: DO NOT USE STOVE TRICK TO STRAIGHTEN ANYTHING ELSE THAN DISC ROTORS.

Thanks hubbers. The pot and stove trick worked a treat. Got both rotors straight.

 

Genuine, so quick. Good to hear.

Hehe! I can't believe we actually got someone to try this 

 

Now that we all know it's safe, we can stop buying new rotors every 2 months!

There was a 'burnt brown residue' on the rotors after heating and cooling. Cleaned it off with some meths. Seem just fine. Going on a nice long ride now, just waiting for my cycling buddy.

Just watch out for the sh!t stain on the rotors after straightening

 

[Guest Big H]

There are rotor straightening tools available. They work, contrary to what the cynics and rich people stated (this include the hillariously funny Hubbers like TNT1 and Hog). I purchased one and successfully straightened the rotors on the tandem. It is basicaly a piece of steel with a few slots at various angles. It takes some time but my rotors are now straightened. The tool is in Angola and I cannot remember who made them. (not Park Tools ar HR said) I bought it at Somomons in Pretoria.

BigH you are right, there is a tool to bend the things straight. ?Park tools makes a good one. ?(Solomon's does not stock parktools usually).

Yes you probably will never get them 100% straight, but it is still expensive to replace them every time they bend a fraction. ?(ie every time you transport your bike).

Use a shifting spanner. Job-specific tools are great but I prefer generic tools. I've fixed a couple of disks using just a shifting spanner. I don't even take the wheel out of the bike, but you do need a stand so you canj spin the wheel and look at the disk head-on.

Re design them to float - one company has done this - seems like the way forward to me then if they are not 100% straight it not a big deal!

 

 

 

But I am a roadie!

A shifting spanner may work but it does not have enough reach. The designed tool has one long slot that reaches the bottom of the disk at the hub, the metal is also contoured that way to reach as deep as possible. The disk is sometimes bent deep down and the tool will fix that without bending the disk at the wrong place.

 

As with pills the generic tool may do the job but then again you are not sure if the generic pills are made in a garage in Boksburg.

 

The Park tool below shows the long or "deep" slot to reach far down. My tool The cycling specific tool I use (and I cannot remember the name) looks very different but also has a long slot.

park tools make a rotor trueing gauge to go with the straightening tool that fits onto the side of a wheel-trueing stand.

Now why would you want to use shiftings , special tools bla bla bla when the stove and pot method works so well . You wife will not even know there is a rotor under her pea soup pot . I have used it more than once and it is easy and fairly fast .

cos cyclists like owning loads of cool stuff?

And they like being seen with their tools in their hands.
