Gen III Noise When Braking

[johnnycakes]

So I am pretty sure I have seen this issue discussed in the forum before but can not seem to find the thread despite searching for quite some time.

I have a 2001 Limited which just started making a distinct noise when braking and occasionally when driving. When the brake pedal is depressed a loud chirp,chirp,chirp sound is made. It also happens intermittently while driving and not pressing the brake pedal but happens every time when braking. The sound also happens in a series of three chirps every time.

Any help or info would be appreciated or a link to a thread describing this issue and the fix.

I imagine it is the brake booster, hoping for easy fix.

Thanks

If its just the noise you just need the accumulator:

This part + shipping + redneck shop charged $30 to swap it out = $160 total

Local Mitsu dealer wanted $165 for the part alone

Noise is gone, brakes work as normal now.

Thanks for the reply. That will be a good place to start.

Hey, I have a similar problem. Mine is only a single "chirp" and it happens when while I press on the brake, and occasionally after I let up. It doesn't happen when I first press the brake pedal, but a half-second or so later, while I'm holding down on it. Does that sound like the accumulator too?

I found a recall on the accumulator, and the description sounds exactly right. I'm going to call my "local" Mitsu dealer (135 miles away) and schedule a service. Thanks SirFrancisDrake for the helpful information.

Thanks for the help guys. The accumulator was the culprit. Fixed and back on road and off.
