Did Rear Brakes on 2010, few complications....

welcome! your 12 v might be low. check the voltage with everything off, after the car sits for a few hours. or the connections might not be clean or tight, especially negative to body.

 

this is normal after 12v disconnect.

 

I seem to remember at a lecture during the 2GoB4 meeting here in the North East (Kimble's Farm, Sept 2014) being advised that even a simple operation such as bleeding the brakes, a relatively easy job (DIY on most vehicles), requires not only specific and accurate technical knowledge, but also specialised equipment if you're planning to do a brake-job on your Prius. (…just sayin' (…shrug!)) - Wil

 

Well, I think you need to look at my whole sentence in order to understand your italicised quote, so that you don't fall into the trap of taking it out of context… …just so that you're not confused…

…and perhaps you will care to enlighten this ignoramus as to exactly how you might do a "simple" job of replacing rotors, pads without bleeding the brake system?

 

Simply two different procedures......either one, does not automatically require the other......

 

no it doesn't. what are you trying to rectify?

 

reading through that, it seems like you're fine unless you introduced air into the system. i would think you'd get some dash lites.

 

I've been replacing brake pads since the '80's, never bothered to bleed the brakes when pushing the pistons back.

@woody23 Maybe you could drill holes in the new pads, for the V-springs?

Also, I'd advise to chock the front wheels, raise the rear with parking brake released, and verify the rear wheels are turning relatively freely. A slight amount of drag is ok, but if it's dragging hard: during rear brake assembly it's imperative to ensure the pin in the back of the pads (they do have pins?) falls in between the spokes on the caliper piston face. And, that it stays there, after assembly.

You want to assemble it right, and then push the brake pedal multiple times, make sure it's well seated, before doing anything else, including reconnection of the battery neg. cable.

If the pads you bought don't have the aforementioned pins, I'd just throw in the towel, get Toyota spec pads, start afresh.

 

The couple of things I'm thinking of: the anti-rattle springs, and their holes in pad edges, and the pins in the center/back of the pads. I've highlighted the springs in yellow, and the pins are flagged with red arrow:



Another pic, the pins flagged with arrows (only the piston side pad actually needs the pin) and the anti-squeal pin hole loc's circled. These are pads/shims I purchased through dealership, for a bit over $100:



I'll attach pdf from the Repair Manual on brakes.

 

I can't see those V-shaped springs doing a lot. (Do hang on to them though.) You can assemble the pads/shims, place them in position on the rotor, then squeeze the springs in and pop into the holes on the pad, take your hand away, and the pads will hold in position till you're able to bring the caliper back and slip it over them.

If the rotors look fine, and the rear brakes don't have heavy drag, you're ok.

Crazy good price btw.

 

Did you happen to order yours from miatoyota on ebay (North Miami Toyota)? I picked up my front and rear set for $95 and am wondering now since I just noticed on the box that there is "Prius EU", though the part number is the 04466-47101. I'll take a photo and post.

I replaced with the anti-squeal springs in between the pads and am thinking I'll take out if they make any noise. I'm also thinking these should be replaced for free since appears to me the wrong set was sent to the dealership by Toyota's Parts Supplier.

I was thinking about drill a hole in also... since seems easy enough... though am like... uhm... Toyota Parts Supplier should know better.

 

Stopped into the Benton Harbor Toyota Dealership and the box is the same for the part number 04466-47101 and the holes for the anti-squeal springs aren't present in the new part number. The old part number that I guess has the holes or isn't an "EU" label is 04466-47100.
