1gen brake swap onto 2nd gen?

A buddy of mine had his front brakes swapped to a 1gen caliper set, but unfortunately the mechanic he went to has since retired and can’t be found but I was wondering if anyone else had any information on the process? Is it a direct swap out with 1st Gen parts? Or would I have to change some brake lines around also? I guess would have to figure out a way to mount them also?

 

Wait you want a 1gen Tacoma breaks on a 2nd Gen?

 

I'm guessing to fit 15" wheels.

 

Yes correct to fit 15” wheels

 

Yes for 15” wheels

 

Downsizing on brakes with 37" tires is inadvisable. But for academic discussion:

2nd gen rotor shows 67.5 mm height: https://www.rockauto.com/en/moreinfo.php?pk=1279145&cc=1432865&pt=1896&jsn=566
1st gen rotor shows 70.5 mm height: https://www.rockauto.com/en/moreinfo.php?pk=1279282&cc=1375343&pt=1896&jsn=724

This means you'll need a 3mm hub spacer between the hub flange and rotor hat to space it out. A 1/8" spacer will probably work. You'll probably have to hunt for a spacer that fits within the ID of the rotor hat, or sand down the diameter of a larger spacer.

 

Def not running 37s anymore haha, but thank you for the input

 

Are master cylinder bore sizes the same between 1st Gen and 2nd Gen? Not going to be a huge difference in front brake torque... but something to think about as the brakes are a system.
