I drove my car today for the first time in about a week and now the right rear caliper won't fully disengage.

1. Does anyone know how we can lubricate the sliders?

2. What else could be wrong? All other 3 tires spin without effort.

 

Not sure where you are located.. but the pads may have rusted to the rotor.. have you tried driving down the street a little, dragging the stuck tire? Usually that will free it

 

yes, i drove it a couple miles before i noticed the burning. The wheel spins, but you have to put a little umuscle into it.

 

this is different.. you should have said something. Sounds like your handbrake cable failed. You might have also warped your disc on that wheel also

 

ok ill elaborate. my car was perfect a week ago, its has done nothing but sit. The ebrake works just fine and i already wore off all of the rust. I think my sliders/guides are rusty and i don't know how/where to lube them or what the underlying problem could be otherwise.

 

The guides are a PITA if you live in an area that sees salt on the roads. I had one of mine sieze but did not know until I replaced the rear pads and could not get the caliper to seat properly..

What you need to do is take the wheel off and remove the caliper from the mount. The Slides are the backside of the bolts that hold the calipers on.

 

I had the same problem, it's the main cilinder within the caliper, I don't know the name, it's an unexpensive part, but I had to get it changed at the dealer because I am not handy when it comes to brakes. They rust, it's not uncommon.

 

what a PITA. i guess i haven't worked on my car enough yet...3 weeks pretty steady and still waiting to finish.
