Brake caliper bolt torque settings for merc a170 cdi im cleaning the calipers and replacing pads, on rear brakes, would like to know the torque settings for the bolts

For front brake pads replacement you only need usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!!
Instructions for front brake pads replacement.
For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
12. Insert retaining spring into brake caliper housing.
Important note: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!!
Check brake fluid level and top up as neccessary!

2. Remove the 2 installation bolts.
3. Remove the caliper from the torque plate.

1. Remove 2 brake pads with anti-squeal shims.

INSTALLATION
Installation is in the reverse order of removal.

1. After installation, fill brake reservoir with brake fluid and bleed brake system.
2. Check for leaks.

If you can't see diagrams(sometimes happens) let me know and I will get them to you

1. Raise and support the vehicle. Remove the rear wheels.
2. If equipped, disconnect the brake pad wear sensor from the harness.
3. Counterhold the lower sliding pin using a thin open-end wrench and remove the caliper-to-sliding pin hex bolt.
4. Pivot the caliper upward or if necessary remove the upper caliper-to-sliding pin hex bolt.
5. Using a brake caliper retraction tool, select the appropriate sized piston press arbor and install the tool onto the brake caliper. Following the tool manufacturer's recommendations, use the tool to rotate the caliper piston clockwise as it is pressed into the brake caliper housing, until it is fully retracted.

Use a thin open-end wrench to . . . . . . support the caliper sliding pin when removing the caliper mounting bolt Use a disc brake caliper piston retracting tool that will rotate the caliper piston as it is pressed into the caliper The rear caliper piston is slotted to allow a retracting tool to rotate the piston when replacing the brake padsTo install:

1. Clean the brake caliper and all sliding surfaces. With the caliper piston pressed fully back into the caliper housing, check for leaking fluid and damaged dust boots.
2. If equipped, install a new brake pad wear sensor in the pad if the plastic part has been worn through on the old sensor. New sensors are not required unless the wire inside the plastic part has been exposed.
3. Lubricate the slider bolts with approved brake grease.
4. Install the brake pads onto the bracket assembly, and then carefully lower the caliper over the caliper mount. Check and make sure that the pad springs are correctly seated.
5. Replace all removed caliper-to-sliding pin bolts and torque to:
6. 1990-97 Passat models: 25 ft. lbs. (35 Nm)
7. 1998-00 Passat models: 22 ft. lbs. (30 Nm)
8. If equipped, connect the brake wear sensor wire to the harness. Check for a good connection as most problems with the sensor circuit are caused by faulty connections. Check that the wire is held by the loop in the dust cover and the connector is held at the clips.
9. Install the wheels and hand tighten the lug bolts. Lower the vehicle carefully until the tires begin to contact the surface and torque the lug bolts to specification in a crisscross pattern to:
10. M12 x 1.5 lug bolts: 81 ft. lbs. (110 Nm)
11. M14 x 1.5 lug bolts: 89 ft. lbs. (120 Nm)

Feel free to contact if you have any questions

Sorry I don't know how I missed it (rear)
--REAR---  wash the brake assembly  depress the piston using a C-clamp Remove the upper caliper mounting bolt Pivot the caliper down for access to the brake pads Remove the inner brake pad and the outer brake pad Remove the upper and lower pad support plates; make sure they are a tight fit and aren't worn. If necessary replace them Install the brake pads in the caliper mounting bracket pull out the sliding pins, cleanthem, then apply a coat of high-temperature grease to the pins and install them. Replace any boots that are worn or damaged Swing the caliper back into place, install the bolt and tighten
