Hey All,

I have a general idea of what's going on with my Jeep, I just wanted to ask the experts for their advice on this issue. Yesterday I was ripping around in town when I stopped at the bank and lost all pressure at the brake pedal. I got out and noticed brake fluid leaking.

For a couple of days I was getting a horrible screeching sound while driving which I just figured was my pads. It now looks to be the caliper leaking at the piston. I'm a single guy who lives on his own and isn't made of money so the less I have to spend to get my daily driver back on the road, the better.

Am I okay just ordering a replacement caliper or will I have to get a rotor and new pads too? If that's the case, will I have to get all four rotors/pads?

The jeep is a 2015 and only has 28K miles on it.

Thanks in advance.

If you got brake fluid on the rotor and pads you would need to replace the pads as well, and either clean the rotor thoroughly or replace it as well.
Brakes are important, not a good place to pinch pennies.

you really wont know till you take it apart and inspect it .
as for the screeching sound...well pads don't make noise

but at a minimum it will need new rear pads.
when you get pads they come in a set and both sides should be changed.
if a rotor is needed just the 1 bad one needs replacement

do you still have the original rotors on?.... If so your not going to have a fun day getting that rear rotor off. the parking brake pad system sits on the inside of the rotor and after a while creates a lip. This makes it very difficult to remove the rear rotors. It took me a can of penetrating oil and an hour of sledge hammering it off.

I would recommend taking the wheel off and checking the back side of the rotor. If its not scratched up or unusual wear, you could just get a new brake piston and pads.

Tools your going to need:

18mm,15mm, 14mm, 13mm and either 8 or 10mm for the bleeder valve, braker bar for the 18mm and a 5lb sledge plus a can of penetrating lube

Oh when you bleed the brakes lines, the only way I have done it successfully is have the engine on and have somebody pump the brakes while the bleeder valve is open. start with rear right, rear left, front right, front left.

Check the brake lines. All of them. Very, very rarely does a caliper fail... but it can happen. Rocks, trail crap, road debris can take out a line pretty easy. My first guess would be a damaged or defective brake line. Still under warranty, by chance if deffective? Yes, the contaminated pad would need to be changed - but best practice is to replace brakes on both sides of their respective axles to avoid pulling to one side, etc. Pads are fairly cheap so do both sides!
