Front caliper piston seals

[G0TB00ST]

Hey Everyone,

I poked around using the search button but was a bit unsuccessful. Long story short... I did my front brakes. I noticed that one seal on each caliper kept bulging out more than the other. I managed to get the driver side on without any issues, but the passenger side caliper got pierced and has a pin hole in it. It started leaking a couple drips of brake fluid so I just put it together and parked the car in front of my house.

Is there a good place that sells those caliper piston seals so I can replace them... or should I get new calipers? I am sure those seals are fairly inexpensive.

Any help is appreciated!

I've rebuilt several sets of the twin piston calipers using parts from Rockauto, Mitsubishi of course sells them too though.

Seals are inexpensive but a bit of work to replace. I've done the pistons and seals once and if I had to do it again, I would probably go with rebuilt calipers which will save much time and effort. The good thing with either way is that you'll get out all the gunk that collects behind the pistons.

Another option is to find a 96 or under Diamante at the You pull it yard and grab the calipers. Most yards sell them for $10-$15 each if you pull them. Just find a nice pair with no leaks and swap them out.

I constantly had to rebuild calipers when I worked at Toyota, 4-runners and Tacomas with the 4 piston brakes are notorious for locking up. I never thought it was that difficult to do, just pop em out, sand the components lightly, new seals and pop it back in. I'd get the seals from the dealer.

OK it sounds like the dust seals have fluid building up behind them. the seal that's leaking is the square cut seal inside that you can't see. replacing the ones you see will not fix the problem. you need to pop out the piston & replace both or in other word, rebuild the caliper.

The rebuild kit is still avalable from Mitsubishi, and its a complete kit.

not to bad a job. I did mine afre years ago when I still worked for Ball Mitsu.

 

[G0TB00ST]

Thanks everyone for you help. I will order the rebuild kit tomorrow. I haven't had the time to do anything yet until now. It sucks seeing the car sit everyday!

 

[G0TB00ST]

We'll the seals aren't available from Mitsubishi and autozone and the local napa can't get them for me. It looks like my only option is buying rebuilt calipers. I really want to drive my baby.

 

[89Mirageman]

You try Rockauto or Advance auto?

 

[G0TB00ST]

I tried advance... I guess ill just order calipers...since I need the car on the road ASAP

wow, that sucks! I had no idea the kit was discontinued.

Rock Auto has them. I looked them up for a 93 Eclipse to make sure they are right for dual piston calipers.

Boost?!? Its matt...

My caliper locked up yesterday. Trying to find out if my 92 Talon single piston calipers will fit if anyone knows?

 

[gvr4ever]

Maybe with the mounting bracket, but it would be a downgrade. I didn't know the single pistons made it past 91. I over heating some pretty decent higher temp street pads with my 91 fwd talon. I wouldn't want the same thing on a heavier car.

 

[thruarod]

93 was the change over point to the twin piston. I swapped to 93 Talon / 3000GT fwd brakes in my Talon, so I have the original single piston calipers laying in the garage so I figured I would put them to use.
