Come along with Eric O. at the SMA Garage as he tries to help out a viewer rebuilding the obsolete rear brake caliper on his 1982 Nissan / Datsun 280ZX. The pistons in these calipers were toast and the parts are no longer made! We also get to see how crappy of a job the "professional" rebuilders did on an Advance Auto brake caliper!

    Why not just swap to different calipers?

    Well Eric, if I were watching you do this live streaming, I would absolutely keep track for you , but unfortunately I don't know when you go live ! But another great video, heck I'm looking for a ac clutch rebuild kit that does cost the same as buying the entire ac compressor for a 2011 mazda tribute 2.5 liter. Have a great day!

  3. Avataaar/Circle Created with python_avatars Ranald Hooper says:

    maybe you could have used a valve spring compressor

  4. Avataaar/Circle Created with python_avatars kodgaf says:

    The snap ring pliers that you need for a job like this are Motion Pro 08-0279 Master Cylinder Snap-Ring Pliers. They are designed to get deep into the bore of a motorcycle master cylinder while leaving room to compress the spring and piston.

  5. Avataaar/Circle Created with python_avatars Mike Bridgeline says:

    Can it be used on a 2021 Telluride SX rear electronic parking brake?

    Rebuilding that caliper could start you smoking! I have a '92 Geo Metro with a sticking, dragging DS wheel. It did not leak, but would not release properly. I took the caliper apart and there was a tiny spot of corrosion on the plunger. Cleaned it all up, but quite the battle to get it reassembled.

    Thanks to your persistence, I stuck with it. Used a C clamp and hammer to get it all together. It works now. sorry for the late post.

  7. Avataaar/Circle Created with python_avatars Jeffery Bye says:

    Wonder why he didnt go see Rainman Ray..lol..guess hes to good for stuff like this..lol

  8. Avataaar/Circle Created with python_avatars Ian La Coste says:

    Check with Scotty he has a huge collection of calipers and catalytics.

  9. Avataaar/Circle Created with python_avatars Rick Carran says:

    You can do it!!!

  10. Avataaar/Circle Created with python_avatars Rich Allen says:

    Put the seal on the piston first!

  11. Avataaar/Circle Created with python_avatars David Streling says:

    knowing no way in hell i would ever try to do this, i still sat here and felt your pain and aggravation and then jubilation at the end as well, i also said a few cuss words for you as well…congrats and thanks for showing this as it really happens

  12. Avataaar/Circle Created with python_avatars Lawrence Anderson says:

    should have ordered the Nissan rear parking brake spring compressor retaining clip installer from Amazon Part number NSC-15389. It looks like a valve adjusting tool and costs 8.95 makes installing the retaining clip a breeze

  13. Avataaar/Circle Created with python_avatars Sid Vis says:

    They are a strugge. I own a 2005 VW Jetta, and with every brake job, I take the calipers apart and rebuild them. That way I'm confident that they're clean and won't leak. I do prefer this kind of ebrake setup as opposedd to the drum in rotor setup. Thanks for the great vids. Greetings from British Columbia, Canada.

  14. Avataaar/Circle Created with python_avatars Dan Sisulak says:

    I am surprised you didn't bead blast that caliper. Kind of a weird caliper…never saw one like that before. Did you get info on it somewhere on the internet? Hope you don't have the flu? (Rainman Ray just did a rusty Jeep brake video…maybe from the beach/ocean water….I'll be doing front shocks on my 2014 Ram 1500…should I replace my control arms at the same time? I already did the rear and put in PU sway bar bushings all around and PU sway bar links…TIA

    For folks that work on their own vehicles, I recommend having a 6in welding/woodworking C-clamp in your toolbox. They're about $6, and work well to hold lots of things while you work on them. In this case he could have kept that spring compressed, using the socket like he did, then put the C-clamp in the vice to hold it while he put the snap ring on. It also makes pushing the caliper pistons back in the cylinder really easy, while it's still connected to the hydraulic system, when you're doing a typical brake job.

    In 1974 had to junk my 1965 Fiat 1500 cabriolet bc no parts. First try at rebuilding a caliper,no good.

    Now I know that I am not alone in the quagmire of auto repairs.

  18. Avataaar/Circle Created with python_avatars ozz mann says:

    Got a question you’d probably be able to fix but not over the internet but I need to try… 2014 mustang GT non brembo brakes.. rear driver side outside pad always wears 2 or 3 times faster.. I have changed pads and rotors 4-5 times.. slide pins, caliper and hoses at least once… still same issue no matter what I do… pins move just fine I NEED YOUR WISDOM

  19. Avataaar/Circle Created with python_avatars Tanker3278 says:

    Might check a machine shop. Can the piston be welded? If yes, the weld a fresh layer around the outside to fill the pitting. Then turn it down to the correct O.D. on a lathe.

  20. Avataaar/Circle Created with python_avatars Randy Stoffel says:

    snap rings? safety glasses please- remember your finger nails

    eric started out watch repairing

  22. Avataaar/Circle Created with python_avatars Michael Basford says:

    Don’t be to hard on yourself. You did a great job. Nobody is perfect and we all get projects that don’t go the way they should. Yes you were frustrated and you had a reason to be, so what. I lover your videos they are detailed and they leave no question of what you did, so we can go back and see what we need to do. Pat yourself on the back. You also have a great attitude, which makes it real. Mike

  23. Avataaar/Circle Created with python_avatars Brian Nilsson says:

    To add love all your videos and your extensive knowledge

  24. Avataaar/Circle Created with python_avatars Brian Nilsson says:

    Why did you not plug up all the holes and blast the rest of it to clean It up?

  25. Avataaar/Circle Created with python_avatars Hola! Don Smith says:

    I know this is years later but a gear puller pressing down on the socket wouldve helped ya get things in the right place.. JS.. Great job anyway..

  26. Avataaar/Circle Created with python_avatars Bismarck San Diego says:

    gotta admit, you scared the living bejesus out of me and i'll just buy new calipers or get someone else to rebuild them. heh

  27. Avataaar/Circle Created with python_avatars Rocky Nix says:

    LoL !!!! Sometimes you have to do things slow to do things fast ..

    Great video. Your grandma taught ya well!!! LOL

  31. Avataaar/Circle Created with python_avatars kevin9c1 says:

    4 years later, I will say I don't think the silicone lube is compatible with DOT 3/4. I think it would be compatible with DOT 5? I did some research because a caliper piston/seal job is in my future and I ended up ordering some Red Rubber lubricant for this job.

  32. Avataaar/Circle Created with python_avatars ExtremeRecluse says:

    I have a 2006 Town and Country that has never had a brake job. Getting all new calipers, rotors and pads. The rear calipers are locked up. Pads never touched the rotors since I bought it two years ago.

  33. Avataaar/Circle Created with python_avatars Chris Bentley says:

    Not only was this a brilliantly detailed explanation but the rebuild was completed for a subscriber. This is the sort of channel that goes above and beyond. A very educational video and no doubt a very grateful subscriber. I've seen the big jobs, the small jobs but this had me transfixed. So intricate. What can I say, I must be a nerd in the making. Way more patience than me and a great video, kudos.

    awesome video my brother.

  35. Avataaar/Circle Created with python_avatars r0bd says:

    You are human after all! Nice work 👍🏼

  36. Avataaar/Circle Created with python_avatars Swanie_64 says:

    That brought back some memories…!! A brake job used to take hours/ half a day if things went sideways. I know the air gun trick… my grade 10 shop teacher taught us how to rebuild calipers. Those were the good ole days. That is why I enjoy watching you… we fix and repair, rather than replace parts. Cheers…!! Ken, Durham Ontario (also part of the rust belt lol)

  37. Avataaar/Circle Created with python_avatars Earl Estes says:

    I’ve gotten deep into some really similar on rear ford calipers where they had a special wrench to adjust them in and made my own tool to do it, because I knew that I would only be doing that job two or three more times before the car would be wore out.😝lol.

  38. Avataaar/Circle Created with python_avatars John M says:

    I know this is old but I just relived Eric’s injury when that piston come flying out. I felt that one. OUCH!

  39. Avataaar/Circle Created with python_avatars Hola! Jerry Williamson says:

    why isn't there a spring on the parking brake lever for left like the right?

  40. Avataaar/Circle Created with python_avatars Leo St Laurent says:

    Great job. Would the tool used for pushing the piston in on calipers work instead of using a screwdriver on the socket for downward pressure ? The videos you make help me out all the time, Thanks

  41. Avataaar/Circle Created with python_avatars Roger Geyton says:

    When I did my callipers I used a rotary s/steel brush on a Dremel flex to clean the groove for the square cut seal. Work really well

  42. Avataaar/Circle Created with python_avatars Rohan Perera says:

    How the hell they put this damn thing together at the manufacturing plant, not like this for sure!

  43. Avataaar/Circle Created with python_avatars brnmcc01 says:

    A trick I learned from my Dad was also that popping the dust boot over the piston with compressed air. We also ran into some very stuck pistons that had gotten a little crooked in the bore and got quite rusty. A trick we figured out when compressed air didn't work, is he had a really big 10,000 psi grease gun. We made a grease nipple that would screw into the bleeder hole, then blocked off the other one with an old banjo fitting, then pumped the caliper up with grease. It was going to come out or break one way or the other. The nice thing with the grease method is, as long as there's not too much air trapped behind the piston, is it won't pop out violently since grease acts like a hydraulic and doesn't compress much. Grease cleans off quite well later with brake cleaner solvent.

  44. Avataaar/Circle Created with python_avatars Paublus Americanus AMERICANUS says:

    What the Eric O. needs to do is put this down and wait for help, even a smaller child strong enough to press down the spring and hold it firmly and pay for their x-mas presents or food to help him. That is the most logical without a root beer capping tool or bullet re-loading press to help said child to give poor dumb dad a hand.

  45. Avataaar/Circle Created with python_avatars Paublus Americanus AMERICANUS says:

    I think this body needs put into an ultrasonic cleaner overnight.
