SOLVED: Troubleshoot: Brakes "Hiccup"

[Vann_DK]

So in the past week, after getting an oil change from the local dealership (not sure if it matters but its info), I've noticed my brakes don't seem to cleanly engage. There is a sort of "hiccup" and the jeep (2018 JL 2door)seems to hop to the left a bit. Not very much, but it's noticeable.

Doing some research, my current theory is that for some reason the calipers aren't engaging in sync, causing this "hiccup" and movement. From what I have gathered a brake bleed would correct this? Maybe when topping off fluids at the dealership something got out of whack?

I would appreciate any insight anyone can give. Thanks.

Doubt topping off fluids would cause this. Sounds like you have a sticky piston in one caliper. You could pull calipers, pull the pads, and clean piston seals with a q-tip and denatured alcohol, then reassemble.

Depending on how many miles you have, it may be time to have the brake master cylinder and lines flushed. I do it at 50k miles or 5 years, whatever comes first.

Bed in your pads and see if it goes away.

Jeeps nearly 5 years old, may be time for brakes. Possibly during inspection the tech inadvertently, or intentionally, did something...

Likely a coincidence it appeared after the service. Check all of the rotors for contamination, discoloration, irregular wear, etc. Any anomoly.

But, yeah, maybe bleeding them might help. There has been many owners who have bled the brake system while activating the anti-skid system, which seems to cure the low spungy pedal on most JLs.

Sounds like a caliper issue. Cleaning will not help. If it's bad enough that you feel service is warranted. Brake issues need to be driven to diagnose , usually a pull to one side is a indication of a faulty caliper. baring you still have brake pads left. Keep in mind if it pulls to the right , the left caliper is hanging up. And the opposite for a left side pull. They are easily replaced and bleed.

So Im only around 30k miles, and there isn't any indication its worn pads. No scraping sound/squealing.

As I am breaking, I can feel it in my foot not catch a little then reengage. There is also a feint sound, not a "clunk" but its definitely there.

I am going to get it checked out by a friend. asap.

SOLVED: Took it in to a Midas. Turned out a wire for the ABS got a little torn up and an exposed wire was making contact with some metal causing the anti-lock system to cause my "hiccup".

86$ for diagnostic and they fixed the wire. Problem solved.
