As important as brakes are at some point it may be time to see a pro. Front calipers du wear, rust internally and need to be overhauled at some point. If you do not remember when rebuilds were last installed it is probably time. At least a thorough inspection during pad replacement and do the pistons retract smoothly. Brake fluid changes do not fix all. As for the rear brakes I have made a number of posts during the years on proper adjustments and parts choices. Check the archives. You should be able to lift the handle ~4 clicks before the shoes drag and 8 clicks to really lock them. Proper brake cable adjustment needs to be done with the drums off so you can see the levers.

A couple of times in the past week of around town driving I have noticed a little brake drag (while at a light for instance or when stopping and starting a lot). I also, after short highway drives I have noticed a slight burning smell a few times. This didn't immediately remind me of typical brake pad smells, probably because I am running some organic type pads up front. In any case I have tracked the problem down to the front left/drivers wheel only. I have not been able to get the brakes to stick while testing but it seems that they have only done this after a lot of town/stop and go driving. The only recent change that my van has seen is a move to coastal carolina where it is wet and salty. I need to get my van out of here before it starts rusting, but that's another story. I have spent months in different coastal areas in this van recently and have never had this problem so I don't know if this is related. Around 2 years ago I replaced most of the brake system including rotors, pads, bearings and hoses up front - shoes, drums, slaves, springs, hoses etc. in back and a new master cylinder and copious flushing. I also dissassembled and cleaned out the balancer/check ball thing at the same time. I haven't adjusted, bled or tinkered with the brakes in quite some time. All friction surfaces are in good shape though and I have plenty of pad/shoe left. A few other details. My parking brake is a bit tight and only clicks once, or twice typically. When doing a lot of city driving I sometimes get annoying brake squeak from the rear wheels I think. This always goes away when I get out of the city. I've only noticed this a few times (Boston, NYC and other similar places where the driving involved a lot of medium speed stops). I'm not sure how to proceed on this one as I shouldn't have a collapsing hose since they are fairly new. I suspect that something is a bit out of adjustment and that either the sea level air pressure or rust has caused the driver caliper to not always release fully. It doesn't bind tightly though and it is hard to notice. My infrared thermometer is really helpful though once it did smoke a bit from that wheel. I hope I didn't cook the grease. It is synthetic so hopefully that is no problem. Any suggestions for adjustments, troubleshooting etc. are appreciated. Thanks, Jonathan Poole
