08 prius The back passenger tire tends to seize up if not drive for a couple days? I have to go in reverse and put in drive (rock the car back and forth) to un freeze the tire? Is this dangerous?Any thoughts?
This needs to be looked at by a professional. That isn't normal and may impact your braking ability (ie. all four wheels may not brake at once and can put you into an uncontrolled spin). Just my 2-cents...
If you've been driving that way a long while, in a gen 2 where regular use of the parking brake is what keeps the rear brakes adjusted, that by itself is a good reason to have them opened up and looked at.
See what happens when you bleed the rears basically everything can stay the same someone sits in the car might as well ready it. They can pump the brake once or twice if they want and just hold it down starting on the right side crack the fitting and see if you get a straight stream of fluid if you do close it up tell your buddy to let up off the pedal pump twice and hold it down again roll over and do the left side it's the same thing happens it seems you've got good fluid No Air seemingly should be okay make note of whether one side squirts a lot more than the other with the same amount of cracking of the bleeder might be hard to notice but if it's noticeable make note because it shouldn't be it's powered by an electric motor that stuff's going to come out quite Stout keep your face out of the way it'll squirt right in your face.
And then is everyone that said when you get it in the driveway and it's still doing this before you do something one morning jack up the side you think is the offending side and see if it is if it isn't check the other side whichever side is the one messing up blast that wheel off . Smack the drum a few times with a hammer not to kill it just to loosen it up see if it pulls off and have a look in there and see if you see anything out of place while to build up shoes almost worn down to the metal that sort of thing? I would have had it done this directly
The drums have M8-1.25 (if I remember right) threaded holes in them where you can insert and twist a couple bolts to 'help' the drums off in a civilized fashion.
My 09 developed a slight brake cylinder leak at around 210K miles, forcing me to do a rear brake job. There was still plenty of brake material on the shoes and the drums didn't appear to have any excess wear or grooves, but the brake fluid made my brakes squeal a little. I noticed there was an excess amount of brake dust built up and circulating around inside the drum. There's a small slot at the bottom, but apparently that's not enough to clear all of the dust that had been accumulating. I'm thinking you might also have some dust circulating around, and that could also be interfering with the self-adjusting mechanism too. Get the drums off, clear the dust, and see how much shoe you've got left. If you don't really need to redo the brakes, maybe put a little dab of anti-seize where the shoes contact the back plate (just pry the shoes away from the plate and add a small amount of anti-seize). Also, check to see that the self-adjuster isn't frozen in place. You may want to check the shoes for rust jacking (rust growing between the brake material and the shoe that prys the brake material away from the shoe) if the car has been in a rust-prone area. My MPG went up by around 5 MPG after I did this. I think it was the extra drag of the dust swirling around between the shoes and the drums.
