Default Any hints on brake pad replacement?

1997 Volvo 850 T5 needs new brake pads all around. Any things to look out for? On my Miata, if you retract the rear piston incorrectly, you trash the caliper. Any similar gotchas to be aware of? Otherwise, is this a straightforward swap? Thanks for any help.

Straightforward, just push the pistons back into the caliper.

Unlike the Miata, there's no hex bolt on the rear. Just use a c-clamp to compress the piston. - AB

Excellent. Last question: is the parking brake a hub/drum type on the 850?

Thanks for the help!

you can trash ANY caliper by retracting the piston incorrectly. put an old pad across the piston (as a flat surface for the C-clamp) and slowly retract it. It's very straight forward.

As far as the parking brake goes, you're asking if its a hub/drum type as opposed to what?

There are parking brakes that are cable driven directly to the caliper, as compared to what he's talking about which is cable driven to a drum setup inside the hub of the disc. On the 850, it's the latter. - AB

It's straight forward, but I had a real problem using a C Clamp to push in the caliper. There is not flat surface on the back of the caliper and it was a pain. I went to Sears and they had a tool that pushed the piston back in the caliper and it was only $11 or 12. I do my brakes often enought to justify paying that. One word of advice, be careful what brand pads you use. I just bought my T5R with practically brand new pads and just took them off tossed them in the trash and put OEM all the way around. Took care of the squealing brakes just like that. I never use anything but OEM on my Volvo's and I've been doing my own brakes since 1985 on Volvo's.

Hi Miatamon,

Haven't heard you for a long time!

Here's a copy from your previous post:

BRAKES:
Brakes on 850 are straightforward, here's the parts you'll need:

GENERAL:
*1. DOT-4 Fluid (I used ATE's Super Blue Racing).
2. Silicone-based grease or CV-joint grease for anti-squeak.
3. A can or 2 of brake cleaner spray.
4. Large C-clamp or 10WR Vise-grip to push back the piston.
*I used Motive Product's One-person bleeder and flushed the system by myself. Available at FCP Groton/Motive Products.

FRONT:
1. New rotors (Brembo or any OEM).
2. New pads (Textar (OEM) or Akebono Ceramic).
3. Synthetic grease for slider pins (The pins are held by 7mm hex (Allen) bolts).
4. New caliper bracket bolts (If the rotor are to be replaced).
5. Bungee cord to hang the caliper.
*If calipers look too worn, you may want to buy rebuilt calipers.

REAR:
1. Rotor (same as above)
2. Pads (same as above, I used Roulands-Dan Block OEM pads)
3. New caliper bolts.
4. New hardware (Retainer springs & pins by Scan tech Sweden).
5. New shims (half-size shims are highly recommended to stop squeak).

●The rotors on Volvos should be replaced at every other pads change. Also, I agree with Jim that I wouldn't use anything other than the OEM parts, and the price difference is almost negligible.

●Make sure to get new half-size shims for the rear, as well as the retainer kit. Also, apply silicone/moly-based grease (cv-joint grease) on every metal-to-metal contact surface EXCEPT the friction surfaces.

●To compress the piston, I use 10WR Vise-grip. Just keep an eye on it to avoid over-compressing it.

●The front pad retainer spring may be a bit difficult to put on, but with several trials & cussing you'll be able to put it on.

●Use torque wrench for tightening the caliper bracket bolts,slider bolts and rear caliper bolts.

●Be careful when you do the rears, as it is not clear as to where you can set the jackstands. I use the factory scissors jack on the side of the body and then put a large truck tyre with the wheel under the body. But wait till someone gives you better method, I wouldn't recommend my method to anyone unless he/she knows exactly what they're doing.

Good luck & be safe.


JPN
