Left Front Brake Smoking and locked up

Took my 2000 TJ out for a little ride this morning, about 2 miles from home it started pulling to the left hard.I turned around and took it home, just before pulling into the drive the left front wheel locked up and went to smoking. Yep, thats a brake. I pulled the wheel after letting everthing cool down, pulled the caliper, and while the pads have plenty of meat on them I noticed both pads were cracked. Not like a factory design but actually cracked in 2 places about 1 1/2 inches from each end. I went to the other side of the Jeep, pulled that caliper, and the pads on it were cracked also. I noticed recently the Jeep developed a hop between 27 and 37 mph, and I'm wondering if these brake problems are what was causing it. I ordered new loaded calipers for it today, hopefully Brown Santa will bring them by friday.

Also order new flexible lines for the front and bleed the brake system

Thanks for the advice, always deeply appreciated.I put new stainless braided lines on him about 6 months ago, and bleeding the system is mandatory. This old Jeep is my work horse, I'm really going to miss him while wating for the parts. Again thanks for the advice!!

It does sound like the caliper(s) had been sticking a while ,that's what probably caused the cracks in the pads . Too much heat will crack the pads ,even if they are good ones. I guess one finally locked up on you, your lucky it wasn't at highway speed! Keep in mind to flush out the brake fluid from time to time, As it gets older in your system more moisture gets in the fluid creating a slushy pedal & eventually gums up your wheel cylinders & calipers wich leads to a failure. good luck with the fix!

I decided to go ahead and change the brakes on the rear too. Gonna do a complete fluid flush for the brake system. I figured I might as well do it all the way!!!

It stopped hopping !!!

I went ahead and replaced the front calipers and pads, even though there was plenty of pad material. Those things must have been the cheapest they could buy because all four front pads were cracked. I mean these were stress cracks, never seen anything like it before. When I pulled the old pads out I could see it was bowed where the piston pushed on it. So I did all four wheels and flushed the system totally added all new fluid. A few months ago I picked up a hop in my front end between 27 and 37 mph. After changing the brakes the hop appears to be gone. Just took it out for a test drive, about 75 miles round trip--no hop!!!

I think if someone has an unknown steering wheel hop like mine, up and down, not left to right this might be something to check out. I would offer this as a sticky, but I am computer illiterate, and just don't know how. But maybe it will help save someone a headache as well as some cash. As for me.... I'm happy, Gonna keep on Jeepin' on.

Any chance this could be a Sticky?

I was thinking it might help someone, if they have a problem like this.
