well the 231 tundra pads actually have a larger surface area so more friction and should be increased braking power as well....

 

pkt1213, did you check the runout of your hub? If your hub is bent you'll soon have brake vibrations again, and probably be blaming the rotors.

Warped rotors is a myth. Rotors just do not easily warp... if you wish to prove me wrong, try getting a cast iron frying pan to warp before it breaks into pieces. Presuming that the wheel face and hub face are flat, lug nuts torqued to spec in the right order, and rotor hat installed properly... I can't imagine a rotor being warped due to heat alone, nor have I been able to find proof of it.

Here's an article for more technical information:

Did you bed in your brakes after you finished installing them? Properly bedded brakes get 20-30% more braking force than those that were not bedded. My '96 runner has never had me complaining about its stopping distance or braking ability... and I'd say my standards are higher than most. If it isn't strapped down, it's getting launched when I lay on the binders, and I can easily use ABS on bare, dry pavement.

Don't get me wrong, the Tundra brakes are an awesome upgrade... but I think the 4Runner brakes don't get the credit they deserve: either through lack of proper installation (i.e. bedding in), or cheap components, or a combination of both.

The install looks good though, nice work.

 

If my stock calipers ever take a dive, I'll be doing the 231 swap. I'm not too keen an grinding my wheels or calipers, though.

 

to avoid grinding do what I did and get different wheels.

I did properly bed the brake pads in. Also to took the rotors to get turned and they turned one but could do the other. I still have them in the garage if you want to see the warped one. It's got the turning marks if you want to see.

 

I've got Pacer alloy wheels and am not willing to change them. Could you please tell me how much wider the 231mm calipers are over the stock 4Runner calipers ?? I've only got about 1/4" clearance between my caliper and wheel now, and am not sure if either 199 or 231 will fit. Sure would appreciate it.

Thanks

Lar.

 

I am not sure but I am going to guess that the 231s won't fit but the 199s are supposed to fit behind the stock ones would work.

 

199s do fit behind stock wheels, or atleast the 2002 sport model wheels.

 

I used the 231 calipers behind the 01-02 5 spoke design with no trimming and no grinding.

 

The stock rotors are thinner than the tundra rotors. Thus the tundra rotors are larger and dissipate heat better. The benefit of larger rotors is larger pad area.
