on rear disc brakes the cylinder actually has to turn back in. careful not to damage cylinder use large pliers to turn it to the left (facing it) until it is far enough to replace the pads.

Are you sure that the caliper piston is the type that rotates to retract, or is it possibly the type that you have to compress with a C-clamp? If you know for a fact that it is supposed to rotate to retract, then it sounds like your caliper will need replacing. If your brake pads get too low, the metal plate that the pad is secured to will begin to heat up from the friction between the rotor and the plate, causing your caliper to heat up and further causing the piston to expand and seize up. Calipers and heat just don't agree. Anyways, if it won't compress, that's what has happened. The good news is that, although you drive an Audi, brake calipers are usually rather inexpensive, so don't be too upset if you end up replacing it. One word of advise that I always stress though: If there is two of anything on a vehicle, I'll never replace one without replacing the other...just a standard I won't budge on. Not to mention, it's nice to have already done the preventative maintenance and trust me...you'll appreciate your rear calipers being balanced too. Hope this helps! Have a great day!

SOURCE: I have a 2001 Volvo

My 2001 S60 just had the same issue. The "check brake light" error message on the dash and the brake lights not illuminating ( the upper center glass brake light would). I found that both bulbs had failed which I replaced. The fuse was okay but still the error message was found on the dash when the brake peddle was pressed. I purchasing a dealer $30.00 brake light relay and the problem is fixed. However, there isn't a diagram anywhere that shows which relay was for the brake light relay. In my 2001 S60, the relay is in the trunk, beneath the driver side removable upholstered cover. The relay panel has ~ 10ea of the same relays and a few other odd sizes. There is a vertical column of relays on the left and right. I found the brake light relay is located between two other relays on the upper right column. It was difficult to reach due to a larger relay on it’s right.

Volvo Radiator, Thermostat and Sensors Your cooling system's temperature controls include all coolant temperature sensors, Volvo thermostat, Volvo radiator or expansion tank cap, cooling fan(s) and fan clutch (if equipped). These cooling system parts function primarily independent of the engine but control the engine either through cooling or by sending control signals to your Volvo's electronic systems.
The Volvo thermostat is a spring-loaded valve that opens and closes based on the temperature of the coolant flowing through it. A high temperature reading followed by a drop to normal temperature (or a continuously low temperature) is a common first sign of a sticking Volvo thermostat. However, many other conditions may cause these symptoms, so you need to know how to eliminate each possibility.
The Volvo radiator or expansion tank cap is also a spring-loaded valve reacting to system pressure. It serves to maintain proper system coolant level at predetermined pressures. It must always be replaced with an exact replacement cap with the same pressure setting. Never use other caps except for short-term emergencies!
A belt-driven fan blade for pulling air through the Volvo radiator is usually on the Volvo water pump pulley and should have a fan clutch to control it. The fan clutch allows the fan to turn with the belt at low engine speed and "free-wheel" at higher speeds. A bad fan clutch either doesn't allow the fan to spin at low speed (overheating in traffic) or doesn't allow it to free-wheel at high speed (potential overheating on highway or reduced gas mileage).
An electric fan can be either by itself (usually front-wheel drive) or auxiliary (used with a mechanical fan). Both types are controlled via a temperature sensor - in the Volvo radiator or upper Volvo radiator hose or on the Volvo thermostat or Volvo water pump housing. This sensor is usually an on/off type switch with a fixed temperature setting. (Some vehicles may have 2-3 settings for multi-speed fans.) This sensor is commonly called an "auxilliary fan switch".
Other common temperature sensors are: 1) gauge sender (variable output); 2) warning light sender (on/off type); 3) lambda and/or fuel injection sensor(s) (variable to control fuel injection settings); 4) thermo-time switch (cold start valve control). Your Volvo may have other sensors as well.
Temperature control is critical to both performance and emission control. Unfortunately, this system is the most difficult to troubleshoot without proper equipment and diagrams. It's even more difficult with computers that adjust timing, idle speed, vacuum and fuel delivery automatically to make up for potentially faulty temperature sensor signals.
Maintenance of your cooling system sensors is virtually impossible since there's nothing really to "maintain". Keeping them clean both internally (coolant replacement) and externally (engine cleaning) is the best way to ensure trouble-free driving. Checking and replacing all parts at the factory-recommended time or mileage limits helps as well

Compressing the rear disc brake caliper on 2008 grand caravan


The rear calipers on these models require a special tool that compresses and turns the piston in at the same time -- most parts stores carry this tool.

It is called a caliper piston press -- and it installs where the pads would go and acts like a c-clamp,when turning handle it will turn the caliper piston backinto the caliper as it compresses it.
Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the Parking Brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor,MILLER Special Tool 8807, . Any other seating method will damage the self-adjuster mechanism.
Good luck and hope this helps.

Compressing calipers to put on new brake pads on 1988 volvo 740


There is a tool available from most auto parts supply outlets, it is a plate that has a compression bolt through it, you slide the plate into the caliper, and tighten the bolt against the piston, then keep turning until the piston is all the way in. These are relatively inexpensive and good to have for next time.

hope this helps.

Unable to remove rear brake pads on Volvo V40 2001


Rear pistons need to be rotated anti clockwise when pushed in.
There is a special tool to do this with, but you could try rotating it with a vice when pushing them in.

This is a verry common procedure for cars with rear disk breaks.
Otherwise the handbrake would not work it they could push themselves in.

Have fun

better off bringing to a mechanic unlike the front brakes,where you can push the piston back the back are different where the piston has to be screwed back with a special tool.
