Just purchased my first LX, and it seems to not be the deal I thought it was. It has the ABS, VSC TRAC, VSC OFF, and BRAKE lights on the dash. Pedal is very stiff, and using two feet with full force yields about 50% of the braking force I get in my IS350. When I press the pedal and start the engine, the pedal goes stays in the same position. No noises at all. Brought it to the shop back here in TX, and the guy at the shop (independent) is telling I have to replace some whole freaking unit (I'm sick, so I admit I wasn't paying as much attention as I normally would to the details of the call...until the cost...) at a cost of like $4000-4500 depending on whether I go Lexus or Toyota. I knew this was gonna be outrageously expensive, but that seems excessive... I've been looking for part numbers tonight trying to find anything near that price. Trying to figure out if he's replacing more than he needs to, his supplier is expensive, or whatever is going on here. His shop has a great rep, so I don't think he's being malicious. Most expensive thing I part I can find in my searching is the "Brake Booster Assy, W/Master Cylinder" (47210L) at $2000-$2500. I plan on calling him in the morning to get a part number and cross check it. Any experience out there?
