F'd up while working on drum brakes. Help?

Totally agree. I need to do this after many years of braided lines on my bikes.

 

Did you try the c-clamp method that was mentioned? Take off res. cap then use c clamp to compress the cylinder. Similar to how you get the pistons on disk brakes to compress when changing fronts. Need to take the shoes off first.

 

With the bleeder open, the OP might be able to press them back in with finger pressure as long as they are aligned. I can do that on my bikes with bigger pistons that those.

 

It's probably fixable. Take the brake pads off, open the reservoir, make sure the pistons are centered and push back in using a c clamp as mentioned. Inspect the seals, make sure they are back in place and not torn. Re-assemble the brakes. Bleed the brakes. A one man brake bleeding kit is pretty helpful. One driven by a compressor is even nicer.

 

Probably easier this way. Excellent point.

 

not sure if anyone mentioned this in the six pages of this thread but backing up does NOT adjust these rear brakes. Making sure they are properly adjusted before putting back together, then always use the e-brake. Using the e-brake is what keeps the rear drums in our trucks adjusted.

 

sounds like a shit show. This happened on my front brakes when I had my dad helping me. Pressed on the brake pedal without the disc or block in place. Grabbed a rebuild kit as it destroyed the dust covers. I have not touched the drums yet but I need to get in there and clean them.

good thread of tips here for drums. One of the things I never touch since they never need any service for years.

LoL! Priuss have drums????? Oh the humanity.

The funny part is that those nerds handled it better than the wrenching truck guys here.

 

Must be an old model. They haven't had rear drums in close to a decade.

I used to gather info there from time to time when my wife had a Prius. Don't laugh. Many of those "nerds" are some serious wrenchin' fools.

 

Just trying to draw a minor distinction.

Yeah, but it is going to be a much smaller percentage in that community. Some neat engineering has poked its head out over there. Homemade plug-in conversions and such, not too mention a couple hot rods and soft roaders.

 

true, I picked up some very good DENSO wiper blade replacements based on some of those Nerds advice on them. https://media.tenor.com/images/cc127125c1e41a3d64d52825f0204dd4/tenor.gif

 

now all that's left to do is a dozen roses for your girl friend followed up by dinner at a really nice restaurant.

 

If the boots are fine it’s fine

Bleed it & go

 

How many miles on your truck? I have 127k and rears were still good. You have a 2017...is the dealer telling you they needed replacement?

 

I cleaned and adjusted the rears on mine at 50k miles and they practically looked new, save a bit of dust. Not expecting to replace the shoes for the foreseeable future.

 

I don't know. Given that Toyota sells thousands more Tacos a year than they do Prius...especially with cheap gas these days...I be willing to bet the percentage is just as high, if not higher.

Sure, the actual total numbers might favor the Tacoma owners. But when you look at the number of Taco vs Prius sales....the percentage is not so different I bet.

I'm tellin' you....there's some serious Einstein wrenchers over there.

 

about 47k taco recall about brake in jan.2019,

 

Even though there is an adjustment. in most cases if the park brake is not engaging well or not holding well its because the brake shoes are not adjusted tight enough against the drum.. by adjusting the cable for the park brake all your doing is not allowing the shoes to retract all the way back as if the park brake is semi engaged even with handle all the way down. 1st thing to do is adjust the star wheel to make sure they are properly adjusted then if you still have an issue with the park brake then the next step would be to adjust the cable.

 

Take the cap off Reservoir so the fluid can be pushed back up
