Dana 30 caliper upgrade

[surf2snow]

Anyone know of an off the shelf replacement caliper that will out perform the stock Dana 30 calipers on stock rotors. Maybe a dual piston caliper or better.
Going on 98 4.0, 35" tires and have disc in the rear. I have also put in a Dodge 2500 master cylinder. So I'm looking to for a larger bore or twin piston.

WJ upgrade.

So any year of the Grand Cherokee caliper will fit?

Search WJ swap

Nothing is really gonna be 'off the shelf'

Wj swap is probably #1 but will require new unit bearings, ball joints, and a slew of other small parts. However if you need to replace that stuff anyway it's a win win

Other option would be black magic brakes.
Awesome stuff there!

Vanco makes big brake kits as well. More plug n pray than WJ swap.

What year Dodge 2500 master did you use. Also what year is your XJ?

 

[surf2snow]

It was for a 1999. But didn't give me more braking power. Just made it harder brake pedal. That's why I was asking about a larger brake caliper. I will most likely go back to stock master cylinder.

Have you tried the black magic brake pads?

 

[XJLI]

the dodge 2500 master is WAY too big for any brakes that bolt onto XJ axles.

 

[surf2snow]

I have not tried black magic pads. I'm using EBC pads and disc.

And thank you captain obvious.

Vanco doesn't make anything anymore.

Black Magic Brakes makes them.


OP:

the most "bolt on" solution is a big brake kit from Black Magic. it will come with everything you need.

nothing else will bolt up to an XJ knuckle.

why did you choose to go to the 2500 master?

 

[surf2snow]

I was trying to upgrade my brake system with bolt on parts.

 

[rockclimber]

you'd be better off going back to a stock master and getting a 15" kit from Black Magic.

 

[surf2snow]

Well it looks like that I'm going back to the stock master cylinder. And I'll keep the larger master for later when I step-up to 1-ton axles. I would rather spend the money on larger axles.
I though/hoping there was a larger brake cylinder the that someone here had the answer.
