96 850 turbo e-brake shoes from local stores longer

Post by johnnyfd »

When I went to replaced my pads and rotors the e brake shoes friction material came off the backings when the rotor hung up on them . I bought new e-brake shoes but they are a little bit longer than the ones that were on my car. The two shoes being about half an inch longer each add up to an inch of extra circumference to fit into the rotor. I can get it to fit with the adjuster but when I try to adjust the shoes so that they have the right tension they seem to catch instead of built up friction and grab. I am concerned that they will lock up in this grabbing manner instead of just sliding or scraping when they are pressing against the rotor when they are just tight enough for the e brake adjustment when its not activated. Does anybody have experience with using a brake shoes that are a little bit longer or understand if the way the shoes catch as I've described can be a problem and will cause lock up? I thought maybe the extra length of metal on the e-brake shoe backing is sticking out just enough to catch the inside of the rotor and that's why they seem to be catching instead of sliding and gradually tightening up as I adjust them . This snagging action only happens when I turn the rotor in one direction which makes me think that something is getting hungup .

If the metal frames are not exactly the same as your old ones then they are wrong and chances are they will cause you grief.

I then bought shoes from another store that were the same length as the first store but the friction material was different. Although they are longer than the ones I had on there the radius is the same. Do you think the proparts ones from FCP or Euro are an exact match

Were the replacement ones that you used an exact match to your originals?

The replacements were an exact match as far as the frames went. I have no idea if the thickness of the friction material was the same since my shoes didn't have any.

For the life of me I can't remember what brand I bought or where I sourced them. I'm fairly certain I had to order them since my local dealer charges list +40% on over the counter parts and I avoid them like the plague. My guess would be that they came from FCP or eEuroparts.

Maybe I'm misunderstanding what you mean by "catch", but bear in mind that the friction you need to stop the wheel from a dude spinning a tire is way, way, lower than what you need to keep a 1.5+ ton chunk of steel from rolling down a hill. Though you feel it as sudden strong engagement, the car might barely notice.

As for length, do you happen to know the brand of the ones that came off the car? Maybe rather than the new ones being long, the old ones are short.

What I meant by catching is that instead of the shoes friction material rubbing against the inside of the rotor and giving the sensation which this would normally give it feels like something other than friction material is getting snagged inside the rotor to make it stop suddenly . In other words I'm fairly easily turning the rotor by hand against the friction material and I can feel it rubbing but it still turns relatively easily then suddenly it snags and will not move another millimeter. This transition happens without any increase in tension on the shoes by the adjuster or by pulling the e brake handle. It's the unexplained transition from the rotor turning fairly easily to suddenly catching on something without any adjustment to the shoes. Then when I start turning the rotor in the opposite direction it moves just as freely as before. If I then start moving in the opposite direction that it was catching before it again begins to catch after moving freely a certain distance

Adjust the,m, apply handbrake hard, then adjust again.

If they have alternating free and stuck spots after that you have the wrong parts
