E-Brake issue "clunking noise" when pulling the e-brake while rolling.

My FRS is about 4,500 miles, and yes i've drifted pulling the e-brake occasionally. Lately I've been hearing a clunking sound when I pull the E Brake while rolling.

I took it to Toyota Kearny Mesa San Diego, and there policy was that they could were not allowed to pull the E brake while rolling??? because that is not the intended use??? they took it apart, the technician told me the brake shoes were glazed and worn. but everything is normal and functional. So I took it on a road test with the Tech and was able to reproduce the clunking sound. He said there is nothing that can be done about it because it still works while parked (intended use).

My question is what is that noise? Is this an issue that Toyota should address? should I get aftermarket E-Brake Shoes? that noise is scary and I am searching for answers. :iono:

seriously...what the shit?

have the same issue

lol

Seems to be normal. It bites hard, and that's all we care about, right?

The real question here is why didn't you find some way to bring it up without letting on that you're doing handbrake turns. ;)

The way I'm reading the OP:

"I raped my stock rear e-brake system and I want Toyota to pick up the tab to fix it all."

its very annoying when rolling through a less than perfectly flat drive-thru line at say In n Out. I dont like standing on the brake pedal so I use the ebrake for that. Each time I slightly engage the ebrake while rolling it lets out a nice THUNK which is more audible from outside of the car. Kinda annoying, but then again this is a cheap car, I think we will have to live with it.

I have the same sound. Figured it was still just "breaking in" but it hasn't gotten better.

Is In n Out your hot pit after a 30 minute session on track? :thumbsup:

I didn't tell them that I was pulling the E Brake while drifting. I didn't want them to have an idea that I was abusing the car. But still the car is only 4500 miles. And I only did it a few times. .

It never did that before..my car is only 4500 miles. .Toyota of Kearny Mesa is trying to dodge the issue. WTF?

Hmmmmmm :D

Only gotta do something bad once to risk warranty. Dealers and techs aren't stupid ;)

Plus, I wouldn't be surprised if the ECU's logged the fact that you pulled the e-brake hard enough to lock the tires while moving at speed.


Remember, there's only ONE way to glaze brake pads: overheat them, badly. How do you overheat brakes? By overusing them... and they don't generate heat if being used as a parking brake.

Parking brake is a drum brake. It makes noise. Nothing is wrong with your car, you're fine.

"The car was driving really slow, like it had a lot of resistance or something, bro. Then I smelled this funny smell!"

Translation: I left my parking brake up when I pulled away.

So there's more than one way...but neither's going to be covered under warranty.

This made me LOL at work. People in cubicles near me wtf'd.

You're not a race car driver during the week?

:brokenheart:

Mortgage banking. I can do originations, so if anyone needs a mortgage... No middleman, no broker, no retail rates, and even better than wholesale rates.

As long as I'm licensed in your state.

NY? I'll need a mortgage by end of summer.

I remember once when I worked at FedEx this guy did his whole route with the parking brake engaged. I don't know how he didn't notice the smell but god was it potent when he pulled in.

You're way less exciting than I imagined :(

This. My car has always done this, it's a parking brake.

As mentioned, the parking brake is just a drum brake. The drum brake uses two half-cylinder shoes that are hinged on one side and pushed apart at the other side to wedge against the inside of the "drum". The pins that keep the shoes aligned rest in elongated holes to allow for this odd movement. It is not precision device, and it's certainly not designed for repeated high stress abuse.

The clunking you're hearing is either completely normal (I've heard it in multiple cars with drum brakes, even normal disc brake pads can clunk from fore/aft movement), or it's caused by excessive slop that you've worn into the mechanism. Either way, I can't blame the dealer for not replacing everything because it's a system only meant to be used while already stopped, not while gently rolling to a stop, or while hooning. I'm sure it's not the mechanic's first rodeo, they see the gamut nearly every day and they can certainly decipher the difference between normal wear, anomalous wear, and abuse. Remember, the 86 is still just a passenger car, not a purpose built competition drift car with a high leverage hydraulic brake system specifically designed to lock the rear wheels.

Solution?
Either A- ignore the sound and keep on keepin' on, and perform frequent inspections and replace parts yourself as needed, or B- Stop misusing the handbrake for hooning.

Oh, and nobody is buying the "only a few times" BS...

Just pretend I'm Ben Affleck from Boiler Room. Ferrari and all. Pretend only though.

You know it's a winner when the thread gets exciting with talk of mortgage origination. ;)

Don't pull the e brake, problem solved

I don't suppose you're licensed in Chicago, the gf and I are going to get a house very soon.

damn I could have used this info. What are your typical costs in closing, fees etc...

Not to get too far on-topic, but...

I haven't really noticed it doing this in my BRZ, but it's not something I do often. However...a few years ago I had a WRX and got massively rear-ended. After that, I had a clunk whenever pulling up the hand brake while not completely stopped. It was a WRX so, no, I never did this to slide. More like rolling down the driveway a couple more inches for whatever reason and using that instead of the pedal. Maybe...just maayyyybe I might have used it to slow down just a tad without lighting up the brake lights. Once or twice. Maybe.

I took it back to the shop that did the repair and they said everything was working fine but since it doesn't happen when stopped, there was no issue.

Still bugged me knowing that something changed.

It's pretty unlikely the drum brake mechanism was damaged in the crash, especially if you were out driving and the parking brake wasn't engaged. Is it possible you were simply more sensitive to changes afterward, and just noticed it more? They may have replaced the whole hub assembly if something was damaged and you got a parking brake that had more wear.

what are the odds this has to do with the rear sub frame contacting the body? from the under car video i've seen that sub frame gets real close to the body under hard braking and accelerations.

for the record my car has the same clunk as the OP and i've never done more than use the parking brake to stop the car rolling down the driveway.

I wasn't really blaming the issue on the crash, although it was nasty. Semi smashed a line of cars and I ended up at the front of it all (I think it was 5 cars, including mine). Pretty much all rear sheet metal was replaced from the shelf back.

I had figured something was different after they put everything back together. I do agree that I was sensitive to EVERYTHING after that. I cringed every time I looked in the rear view, and kept thinking I'd find a boost leak any moment...

That car is long gone now, though.

the e brake is intended for use when the car is stationary. not rolling. hence the clunk......maybe

looks at username...

It's possible, if the brake can grab hard enough to lock the wheel then it can apply as much braking torque as the disc. I'm pretty certain the clunk most people are talking about is from the drum pads slightly clunking fore/aft under much more subtle circumstances when moving slowly, such as driveway or parking lot speeds, at best.

I have the same ebrake clunk. I never abused the ebrake. I likely heard it the 1st time I was slowly rolling to a stop to park and pulled up the ebrake while the car was still rolling. Happened since day 1 and still doing it. None of my other cars are this loud. I thought it was originating at 1 rear drum? The noise is irritating and seems cheap. I think it is silent when rolling backwards and applying ebrake?

This should solve the clunk.

Will this be covered under warranty? :burnrubber:
