Metal scraping noise when getting out of car

Hi everybody,

Often when I have the e-brake set and get out of the car, i.e. my weight of 190 lbs comes off, there is a scraping noise from the driverside rear wheel as the car rises a bit. I assume it is the parking brake shoe that "slips" and make that noise.

From a search I learnt that I have to remove the hex-bolt (7 o'clock in Picture) and then loosen the parking brake shoes through a bolt hole to take the rotor off. Do I need to unhook a cable?

Has anybody experienced this kind of noise and found a solution to it ?

Thanks in advance.

The lower hose I believe is the brake cable. Does that need to come off?

Thanks Manny,

As they say: A picture is worth a 1000 words...

Hopefully somebody will chime in as I hate to take it apart without any idea of what will happen.

I looked at the passengerside this morning. (I am checking the rotors for thickness, as the front needs replacement). There is a bolt that seems to hold in the brake cable, but there is probably something else inside. (see picture)

The e-brake seems to be ok on this side. It didn't make that much noise when lifted and I cannot turn the rotor after 2 clicks on the e-brake pedal.

Thanks again

Reinhard

The rotor should come off with a little wiggling with the park brake disengaged. I've had no need to slacken the park brake adjuster and definitely no need to detach the cable. As it is I don't think you can detach the cable without removing the rotor. You'd have to drive a long way with the park brake engaged to wear a groove into the drum.

If I didn't have the rotor off to see the park brake adjuster, I'd never have figured out how to turn it using a long screwdriver through a lug bolt hole. Even with the manual showing how to do this.

Thanks Sixto,

I found the adjustment position on the passengerside with a fllashlight. On that side, the hole has to be at the 1 o'clock position. The picture shows barely the shiny metal adjuster nut inside (see new picture).

So I need to take off the caliper, the hex nut and then pull it off towards me with a little help of a hammer, in case it is rusted a bit?

Thanks again

Did you adjust the park brake and it still makes noise? Can you turn the wheel (either both rear wheels in the air or one wheel in the air and transmission in neutral) when the park brake is engaged? It might be something else such as the subframe mount.

Hi Sixto,

When I did look at the driverside yesterday afternoon, it was more for measuring the disc thickness (9.4 mm) and seeing how it comes apart and taking the pictures. I did not check the function of the e-brake. This morning, when I checked the passenger side, I checked the e-brake by putting the transmission in neutral and releasing the e-brake. I could spin the rotor with some resistance (I guess thats normal). When brake applied 1 click, I can still spin, with second click, no more. I did not adjust anything as that side seemed fine.

I'll have to do the same for the other side, but there has to be something wrong on the driver side with that type of metal to metal noise when I get out of the car.

The subframe mounts have been replaced a few months ago without any effect on the noise.

I'll let you know when I open it up, probably Monday.

Thanks again

Reinhard
