Cheap-SOB question of the day...

 

I have a salvaged rear caliper I'd like to rebuild, it has some pitting, almost all of it beyond where the square sealing O-ring will need to sit or travel over, but with a little where I think it will need to go.

 

Is some pitting tolerable? It will polish to where it has no bumps.

 

Can you get pistons?

That piston is garbage.

Get a new one from the dealer.Around $25.

With the price of a new caliper (the rears aren't that much, are they?) I might go 15 for a piston, if they are 25 I'd just go for the whole caliper.

 

Thanks.

The bore is in good shape, the bleeder came out, if I end up not using it maybe someone out there can use the caliper if they have a decent pistion.

 

I might get really lucky and might only need one caliper, the one for which I have a replacement! I think only one of my rears is dragging.

Hmmm, 15 bucks.

5 bucks for the kit.

40-50 for a whole caliper.

 

Undecided...

Wow, what's tough to find is a hardware kit, I basically need everything inside the e-brake drum (all mine is rusted to death).

 

Rockauto has one kit, from england.

All the springs and the hold-downs, that is, the rest is in rough shape but usable.

 

Need to find a good paint for those things, maybe just rust converter.

What year and model are you working on?
Rockauto lists all that under "Parking brake hardware kit".

I didn't see that, except for the one hw kit from england. I'll have to scour the site better.

Yeah, I see it now. Silly me, was focusing on 'rear brakes', didn't guess it'd have its own listing.

yeah i wouldn't use that piston, that's terrible.  i just rebuilt a caliper last week.

 

i'm sure folks have extra calipers they could send you one or a piston?  i don't think i have any rears...maybe?
