I've tried many combinations of search lines to find this information but I can't seem to.

I was given a 2015 Cherokee Latitude and I am doing all maintenance on it as it has never been done, outside of oil changes. The brakes are SPONGY and I was looking up parts to replace them and noticed that some Cherokees, I'm thinking V6's or 4x4's, came with 2 Piston front calipers. My current Jeep has a single piston. Is it an easy swap to do for an upgrade or should I stick to just the factory single front and rear. Any advice would be much appreciated. Thanks!

 

Is there any way to see the shape/size/bolt patterns?

Go to a local parts store and ask them to see both and compare them would be my best option if nobody on here can offer anything

If they are really spongy, have you bled them yet (you just didn't mention if you did or not) , but I'd bleed them, and if they're still bad then look for worn out rubber lines. Would be annoying if your upgraded calipers and they were still squishy

 

I have a 2015 Jeep Cherokee sport utility (front wheel drive) I have to buy front brake pads and rotors and I'm trying to find out if I need to get single or dual piston calibers. Would greatly appreciate any assistance!!

 

I don't believe the FWD version had the dual-piston calipers. To confirm, look at the caliper and see if it has a single rounded area on the backside or two.

try maybe an aftermarket caliper with a dual piston setup.

 

Single or dual piston calipers need to be matched with the master cylinder. Adding more surface area at the piston will add more pedal travel, and you may end up decreasing your braking if the pedal is hitting the floor before the master can move enough fluid.

If the brakes are spongy, you need to bleed them better. Also make sure you don't have left/right calipers swapped which will prevent getting all the air out of them. If you want better braking, try better pads.
