It has a lot to do with tire height too. If your stockers are 29.75" tall and you put on 31" tall tires you will increase the torque on the brakes as well. It also depends where the bulk of the weight is. If a 16" wheel weighs the same as a 20" wheel, the 20" wheel will be harder to stop because the weight will be further from the center, increasing the force of torque on the brakes. ( I don't know if this may help understand) Like, if you put a rod through the center of a lawnmower tire and spun it and tried to stop it only using the rod it woulden't take too much effort. But if you did the same to a bicycle wheel that weighs a lot less it would be harder to stop due to the weight further from the center.

I agree with you Snafudilligad I'm just adding info
Now its beer time

 

I was looking at this baer 14" upgrade myself.

The question I have is what happens after you can not cut the rotor any more? Where do you get a 14" rotor? Do you have to buy the whole damn kit again?

And good info it is!

I completely overlooked (even though you can retain the same overall wheel height) that the weight being further out from the center creates more centrifical (sp?) force and thus, more difficult to stop with more weight toward the outer area of the wheel.

Duh Thanks.

 

On a cross drilled rotor I dont think you will be "cutting" at all.

So yes, once shot, you buy a new rotor. You cannot resurface a cross drilled rotor (unless something changed recently I am not aware of).

 

So that will cost $600-$700 everytime. Forget it.

Unless you do something to destroy the rotors or have some type of a problem the rotors will last along time. I had a Dodge Dakota with 300k on it. Replaced the brake pads several times. Never had the rotors turned because they did not need it. Should be a one time expense. Baring problems they will last longer than you probably plan to keep the truck.

 

We have never had anyone have to replace a Baer rotor. As long as you keep good pads you should be fine. If something did happen though, we could get you a single rotor.

 

How much do replacement rotors cost? This might make it viable now.

BTW. Can you get slotted replacement rotors or do you have to use the cross drilled type?

=Dave

 

I will have to call Baer & let you know what I can do for a single rotor. As for a slotted rotor not cross drilled I can get them for you from Stainless Steel Brakes!!

 

What size rotor should you get if you ahve 20's but may still need to use the 16" spare. IS there a certain size for this or a certain procedure?
