Grumbling Sound When Braking

[Skizz]

Hi all,

I just test drove a 2000 SC 300 that I'm contemplating purchasing. It appeared to be in great condition, except that I noticed, upon braking at lower speeds, that there was a grumbling sound that could be heard and felt underneath the seats. Any ideas on what this could be?

I'm having my mechanic check it out on Monday before making the purchase, just thought I'd post and get some of your opinions as well.

Thanks all,

Scott

Could be the brakes grinding ,needs to be changed. Metal on metal.

Check how much is left on the pads. Check if there is debris stuck in between the pad and the rotor.

Of course it could be brake pad/rotor noise, but it could also be lower control arm bushings. Have someone apply and release the brakes going o to 1 mph, repeatedly. Watch the front wheel. If it moves front to back, it should be LCA bushings.

Good luck

Well, for me it was lower control arm bushings (front) and thanks to Gordon at Carsons Toyota I got a pair of Supra LCA's delivered for $476. I tried to DIY but I couldn't get the ball joint apart, so I had my local indy mechanic do the job. Huge difference. Feel like a car 10 years younger!

Rusty Rotors?

Happens every time my Charger sits for a while. Goes away with some braking.
