Hey all. Doing the brakes and found one of the two pin bolts that goes into the rear of the caliper is completely seized up. Looks like, after peeling off the rubber boot, the thing is rusted. I've tried using a chisel and knocking it back out of the hole with a hammer. If I somehow get it to come out, is it better to just replace that caliper than to grease the hole and put a new pin bolt in? Looks like the rubber boot is crammed into the hole so I may not be lucky enough to get it free. I worked on it for literally 2 hours last night and no movement. Might put some heat on it. Trying to avoid paying for another caliper, but I'll do what's necessary, obviously. REALLY glad I have my old '91 Integra for times like this.

Also, just in case it comes to this, I found one on ebay (right rear assembly) here: Acura TL 04-08, Rear Right/Passanger, Brake Caliper, 43018-SEP-A00, Factory OEM | eBay
What's odd is that the part number from Acura parts online has this as 43018-SEP-A51 but the ebay part is 43018-SEP-A00. I'm guessing this is just because it also comes with the piston whereas the A51 is just the outer piece?

 

what year is your car?

 

Could've included that info, couldn't I? lol..

2005 MT Base.

 

It would have been helpful

According to www.oemacuraparts.com, 43018-SEP-A51 is the proper part number and looks like it includes the whole caliper and bracket


and according to the same website, that 43018-SEP-A00 is meant for the AT TL. I thought the brakes on those were interchangeable though..

To remove, reinstall the caliper bolt into the seized up slide pin and use a hammer to remove it, then you can drill out the rust with a drill brush or something similar and regrease with brake grease. you'll want a new caliper bolt and slide pin at that point though.

you can also get an aftermarket caliper at RockAuto

 

This one is 40 some odd dollars on ebay. It'd be good to verify whether they are interchangeable. I'm not real sure why a transmission would make a difference in brake parts.

 

Ok, so I just got off the phone with an extremely helpful parts guy at the AutoNation Acura dealer in Clear Lake (South East Houston). He said he would not chance getting the A00 since it's for CL & TL's from '01-'08 and the A51 is for the Type-S which, even though mine is not Type-S, he considers it a superior part. I sent him the link to that ebay item and he said even though they look quite similar, he wouldn't chance it. I found one for $65 that's the identical part number. Their price for an OEM one was $202. Ouch!

 

When both of my rear calipers on 08 TL was seized, I bought 2 used calipers off ebay that said came out of a CL and it worked. Got both for $50 shipped. Don't know what's wrong with the one you link, it looks fine to me, but ultimately it's your call, $20 difference for a piece of mind I suppose.

 

To clear it up, he said Type-S parts are on my car, despite it not being one. Specifically, the brake parts and suspension. That sound right to you all?

 

Hazsun, I'm with you. I'm tempted to just buy the cheaper one and put them up against each other to see if there really ARE any differences. I'm still on the fence about it.

 

AFAIK, rear brakes are all setup the same on these models, maybe better quality? But you're buying it used. I know that your front brakes are Brembro because I have a friend with 04 MT TL, and it has brembro for front brakes. Type S also uses Brembro for front brakes.

 

I ended up buying the cheaper assembly for $45. If anyone's interested, I'll take pictures of them both side by side and note any differences between the part numbers. My guess is they'll be identical, but time will tell.
