Ok, I've searched for this and couldnt find the answer to my question.

I have a seized rear caliper. Now when I replace it this weekend I know I have to bleed the caliper to get the air out. Now do I have to do all the other 3 or just that one?

i would personally say do all 3 to be sure, but i'll wait to see if anyone else chimes in. whenever i did work on other cars i always did all 4 wheels, although since this car has ABS maybe it's designed in such a way that you don't have to. if you're allready in the garage with your tools it won't take you long to do the rest. and if it was seized while driving you should replace all the brake fluid since you could have boiled it, thereby destroying its hydraulic properties.

 

You only have to bleed the entire brake system when disassembling the ABS or the brake master cylinder. When servicing any one of the calipers, only that caliper has to be bled.

However, if you're near the time for a brake fluid change, you might as well do it now too.

 

When is the last time you bleed and change the fluid ? If recently then you do not
need to do 4 .. if more then 2 years then do 4 will not hurt especialy when we live
in Canada.....

 

I bled it in August when I replaced the front calipers with the "Legend" dual piston, replaced the lines with Stainless, and painted all the calipers. I noticed that the rear could or should have been replaced when I did the work in August....I hate when I'm right!

how did u notice that you had a problem with the caliper? just curious becuase i'm thinking mine could be messed up too.

 

When I got out of my car, I noticed a smell like burning brake pad. I checked around the car and found it to be coming from the rear passenger wheel. Extreme heat came from the wheel well. Even when I washed my car I noticed that the water would steam and evaporate right away if I sprayed it on that rotor not to mention the amount of brake dust that washed away. The other rotors werent even hot compared to this one. So I would say it is seized.

Would it be working to hard and get hot while the other side getting seized? The best way is to jack up the wheel and turn it by hand and feel if it is seized ?

 

I thought about that, but I'm going with the theory that it is seized on the rotor and will not let up once the pressure is released with the brake pedal. Also for the heat that it does produce, the fronts work harder than the rear so I doubt that its what you maybe suggest.
When I did my brakes in the summer, I did notice it was a little bit of a pain to squeeze the piston back in when was ready to reinstall. So I should have replaced it then....but I just spent a few buck on the front for the dual piston type.

I'll know for sure if it is the one when I take it off tomorrow. I plan on replacing the driver rear soon anyways, when its warmer and when I can afford it....my god...the price for calipers even for the rear!
