Park brake questions

Ok I have done park brakes on older volvos. I think my left rear shoe has separated. My R is still under CPO warranty, but dealer is 120 miles away. I want to pull rotors and check it out myself. I think there may be more wrong with it than just the pad separated because it sounds bad when I pull brake lever. My big question is will I be able to get all the pieces put back if it has exploded so I can get it repaired under warranty? Will shoes from a 240 or 740 fit if it is just separated shoes?

Re: Park brake questions (vlvman)

I feel like a read a couple of threads on this where Volvo not only didn't cover the replacement of the pads under warranty, but also didn't cover the damage to other parts from the de-lamination explosion.

Adjusting the handbrake
Note! As the illustrations in this service information are used for different model years and / or models, some variation may occur. However, the essential information in the illustrations is always correct.

Adjusting the handbrake
Detach the dust boot on the handbrake lever (pull straight up).
Fold up the plastic cover.
Adjust the handbrake.
Note! Full brake effect can be obtained between the second and fifth ratchet teeth. Check so that the handbrake is not constantly applied.
Note! After replacing the brake shoes for the handbrake the car must be test driven and the handbrake adjusted if necessary.

Bend the brake shoes apart and remove them with the return spring and spacer.

Cleaning and checking
Check that no grease has leaked out of the wheel hub.
Check the handbrake expander for damage. Lubricate if necessary.
Clean the surfaces of the brake drum where the brake shoes make contact.
Check that hub flange is clean. Remove any rust.
Lubricate the contact surfaces on the brake shield. Use heat resistant grease, P/N 1161325-4.

Installation

Install the brake components
Install:
-the brake shoes
-the spacer and the small return spring on the brake shoes.

Installation brake components, continued
Install:
-the lower mounting spring. Press in the spring (1) and turn it slightly (less than 1/4 turn)
-the upper mounting spring. Check that the brake shoes are in the correct position in the expander

Re: Park brake questions (zabto)

I thought from what I read they covered all affected parts on that side of the car but if they replaced the rotor or other matched parts we had to pay for parts and labor on unaffected side.
Does anybody know about shoes from older cars fitting the R? They were interchangeable from model to model.

I'm bringing back this thread because today I attempted and failed to replace my parking brake shoes and return springs. I am very accustomed to working on cars, I do it all the time, but I haven't played around with too many drum in hat parking brakes. I go the caliper and rotor off and tried to remove the shoes per the instructions above and I couldn't remove the small securing springs that hold the shoes to the heat shield. I used needle nose pliers to push them in and turn them in both directions and neither would come out. I could destroy them but I don't have replacements. Anyone else have that much trouble removing these securing springs??

Re: (VOGZ)

What you are refering to is commonly called the "brake nail". You need to reach in back of the backing plate, and feel for the brake nail, and not allow it to get pushed out as you are pushing in on the spring and retaining cup. Examine the cup, you just need to turn a quarter turn, and you will see a slot, where the head of the nail can pass through. That will allow it to be released.

I should add that if I am understanding you correctly, it is part #13 in the diagram shown in this thread.

That's affirmative. Part #13 is a little beotch. I'll take it back apart later this afternoon and try again. Thanks for the tip.

I just did mine.

1st - get new springs, including these PITA ones. Why? Because they're only a couple bucks, so well worth it.

To remove the spring that holds the shoe in place:

1. Using needle nose pliers, push in on the spring.

2. While pushing in on the spring with pliers, use a flat head screwdriver between the shoe and dust cover and pry open a space between the two.

3. While doing 1+ 2, look in the space created between shoe and dust cover and locate the spring that you're pushing in - it has a hook on the end that goes through a slot on a bracket that's part of the dust cover or whetever holds it on the backside. Then, use a 2nd flat head screwdriver and help pry off the hook from the bracket. Once off, use the needle nose pliers to guide the spring out through the slot.

If you get new springs, you can simply cut these SOBs clean off...they are much easier to install than to remove, however, when installing, use a flat head screwdriver to create a space between shoe and cover so you can visually verify that the spring's hook is hooked on right through the slot.

I would open (take rotor out), clean out the broken pieces, collect them in a bag and take it to the dealer. No need to take anything off (shoes, springs, etc.). Just don't use the e-brakes!

On the other hand, if you do that, the dealer may try and say "well...someone got in there, so we don't know what was done and therefore, cannot cover under warranty"...up to you.

Re: Park brake questions (S60R1)

I just did mine today and those springs are a pain in the rear. I got most off by pushing in on them and sliding it along with the shoe without using pliers at all. BTW what a difference! I used to get crazy e-brake noises and it would jam up when parked on an uphill. Works extremely well now with the new shoes, didn't expect to make this much of a difference.
