Took step sons 92 bonneville to sears the other day to get brake system flushed. Had never been bled and felt it needed doing, but was worried about busting bleeder screws since in 15 years it hadn't been done. (at least it appeared that way). Anyway, they tell me about 1 1/2 hours to do it. We walk the mall and get back after an hour and 5 minutes, car is on lift, wheels off and no one around it. Wait another 45 minutes and still nothing, go to desk jockey and ask what is going on. About 10 minutes and the manager comes up and says the master cylinder is leaking (blowby). I ask why they didn't call me and tell me instead of leaving me here waiting and he says they usually call and try to find the part before notifying the customer. I tell them that is BS, they need to notify the customer first and ask what the customer wants to do instead of wasting their time. Told him to put the wheels back on and give me the keys, I would replace the master cylinder myself. Well, get the keys back and drive off. Don't even get out of the mall and hear a thumping noise every time I hit the brake. Get out and make the GF drive by. Left rear wheel wobbling like crazy. Take it back and throw a big fit. He has custom wheels that are fitted to the hubs so the center of the wheel is different on the front than the back and they switched the wheel. The front wheel won't snug on the back drum. What a bunch of incompetent boobs. So, go to Autozone, get a replacement, go home, pull the old one, take the new one out of the box and it has a busted resevoir. Jump in the other car, back to AZ and get a good one (last one they had) back home and get it done. I wasted the whole day on about 2 hours of work.
