Wobbling and burning smell problem Options

[smiffythecelica]

After 20 minutes driving on country roads at 60mph I've gone into a town area to drive at 30mph and after 2 or 3 minutes the car has started wobbling/vibrating up and down on perfectly flat roads. The wobble even occurs when I have the clutch pedal full down (i.e. gear not engaged at all). This is accompanied by a burning smell which is coming from the front of the car (don't know where exactly).

This has happened 3 times over the last 6 weeks. After the car's been allowed to sit still for a few minutes the car drives fine again. I don't have a worn out clutch as I've tried accelerating hard in 5th gear and the revs don't jump.

I've had Mr. T take it for a test drive and have a look over it and no problems were found. Any ideas? Don't know if it's related, but there is a rattling sound under the bonnet that I get when the engine is cold.
Cheers,
Dave.

Rotors and pads are not that hard to change and yours are probably toast if they got really hot., 1st thing would be to try to verify what he said. I'd jack it up and do it yourself. maybe have someone press the brakes and let off, see if both wheels spin free immediately after releasing the pedal. let is sit a while and see if either one turns easier Maybe bleed the brakes, be sure you get fluid out both sides easily. I still suspect it could be a brake hose collapsed internally. Does the car intermittently pull to either side? that would be a good indication one side is sticking. SOMETHING is sticking for one side of yours to get hot. Whether it's the caliper slides or hose problems or something else is the question ( I learned about bad hoses on my truck. After replacing rotors, pads and Calipers due to the same symptoms you have, one side wouldn't bleed at all. the rubber hose had swelled up inside and was not letting the fluid return, keeping the pads against the rotor) could have saved a bunch instead of just assuming the caliper was stuck. IIRC the Toyota caliper pins have dust boots and shouldn't stick all that easily unless they were re-assembled without grease in the past.
