Front Caliper Siezed

Does your Mitsubishi L300 make a strange noise? Need wheel alignment specs?

Front Caliper Siezed

Post by Jensen »

On my wife while she was driving around. I'd noticed a sound every once in a while while braking from the front left and that wheel seemed to be generating an abnormal amount of brake dust. It was amazing how fast it went from a minor annoyance to wow no brakes! Anyway, my wife's been a bus driver for more than 10 years so it wasn't an issue, and she was fortunately in Richmond at the time so she got the van into CVI (Thanks Butch and Christine!) But this is just a heads up to anyone else out there that hears a scrapey sound while braking and sees one wheel much dustier than the others. Take the wheel off and check those caliper pins! I wish I had, half an hour worth of work could have saved me $300-$850 worth of parts and labor (depending on how bad it is, I'm actually kinda hoping it's bad enough I need to replace the caliper as I'm wanting to do a dual piston swap anyway... However after a discussion with Christine I'm now re-considering it. I have to send some e-mails and do some serious homework before Monday!)

Again, thanks CVI! :-D

Even if it feels like your tires may be out of balance or the rotors are warped, the sliding pins may just be the culprits.

By design, they will rust and sieze up. It's just the way they are.

So pull them out and check them one by one.

Ideally, you want them to be very smooth with no ridges or rust.

Usually when replacing the brake calipers, if they are a full or partial kit, they should come with the mounting brackets to the spindle and new sliding pins (bolts).

This applies to both L300 front brakes and L400 front/rear brakes.
