How do you replace rear brakes on a 98 Volvo S70

What is the problem with your emergency brake?

If it is the shoes, you just need to remove the rear brake rotor to access the e-brake shoes. If it is the cable that needs adjusting, you can access it by removing the center console.

Sounds like your rotors are warped,, if you installed new disc brake pads and DID NOT turn the rotors.. there is a good chance they DO need turning...

PARKING BRAKE IS ADJUSTED THROUGH A OPENING IN THE ROTOR ON TOP.YOU NEED A LONG ALLEN WRENCH LOOKING TOOL TO FIT IN THE SMALL HOLE TO LOOSEN PARKING BRAKE.

Rear brake rotors out of round , they need to be resirfaced or replaced.
If pads are less then 60% , replace pads also , otherwise clean them with send paper.

sounds like wheel bearing but first check that brake is ok and not binding check pads for excessive wear spin the wheel listen for any noise from bearing if bearing worn see my solutions for 850 volvo bearing replacement same as S70

if you managed the front ok, the rears will be a walk in the park good luck steve

1. Turn the ignition switch OFF and, if equipped with ABS, remove the key to prevent accidental pump activation.
2. Raise and safely support the vehicle.
3. Remove the wheel(s).
4. Disconnect any ABS wires, if equipped.
5. Clean the brake caliper thoroughly and remove the dust caps from the bleeder nipple.
6. Open the bleed nipple and lock the brake pedal the depressed position. Collect the brake fluid spillage in a suitable container.
7. Remove the brake pads and disconnect the brake pipes from the caliper.
8. Remove caliper mounting bolts and lift the caliper off.
9. Drain the remaining brake fluid in the caliper into suitable container.

To install:

1. Clean the caliper mount where the caliper lies.
2. Install the caliper and new mounting bolts. Tighten the bolts to 44 ft. lbs. (60 Nm).
3. Connect the brake line to the caliper and tighten to 10 ft. lbs. (14 Nm).
4. Grease the brake pad shims with a thin layer of silicon grease. Put the shims on the back of the pads and install them in the caliper.
5. Install one retaining pin, spring then the other retaining pin.
6. Fill the brake master cylinder and bleed the brake system.
7. Connect any ABS wires, unfastened earlier.
8. Install the wheels.
9. Lower the vehicle and check the brake function before driving.

Good luck...

could be a bad outer tie rod end or lower ball joint on the front suspension, to check jack up wheel (suspension supported) grasp tire and move back and forth, if you feel loosness you have a worn component. if there is no looseness then you have either an bad wheel bearing (excessive runnout) or defective rotors

did you replace All discs front and rear? if not , replace the ones that you previously didnt

look for a rubber protective cap and remove it. Use an allen wrench to unscrew the pin.

if is when you brake than you have to check out first you brake pads material
