Advice on Changing Brakes and Serpentine belt

One belt: TOYOTA OEM 04-09 Prius-Serpentine Drive Fan Belt 9091602570. I bought one at my local Toyota dealer a week or two ago for about $12 including sales tax.

Changing belt involves two fasteners: i.) hold down bolt on tension adjuster; and ii.) adjuster assembly. IIRC correctly one has a 13mm head and the second has a 14mm head. See pics.

The warranty is $36 extra?

I would check the rotor runout and thickness against spec (see attached), and if they look good are meet specs, just leave them be.

Brake calipers I wouldn't touch unless they're obviously problematic. Lube the glide pins. Aftermarket Sil Glyde Brake Lubricant is what I've been using, no problems, but there is a proprietary Toyota grease. For pad contact point I like Permatex Anti-Seize. Again, there's a proprietary product from Toyota I believe.

Considering this is something you might do once in the car's lifetime, I would stick with Toyota parts.

 

Yeah.

 

Calipers are generally replaced if leaking or stuck. And, rotors are generally replaced if they are too thin or are excessively warped.

Have your local auto parts store (reputable and full service) check brake rotor specifications and recommend whether rotors should be replaced. Leave calipers alone unless leaking or piston jammed in caliper bore. Just my two cents ("$0.02").

 

Toyota has three different versions of front brake pads for the Gen2. This issue has been discussed in depth (including part numbers and price) at the following thread: Which Gen2 Toyota Brake Pads Are the Right Ones? | PriusChat


Alternatively, Rock Auto has some incredible deals on rotor and pad combination sets. For example, Rock Auto has two new rotors and brake pads for about $36 (plus S&H). All the way up to $130. See: 2006 TOYOTA PRIUS 1.5L L4 ELECTRIC/GAS Rotor & Brake Pad Kit | RockAuto

PS My experience is that low cost totors do not last as they typically warp from heat and then need to be replaced again. OTOH, the law of diminishing returns says that you will receive more incremental benefit for the first one or two incremental increases in price over the minimum. Average price for six sets sold by Rock Auto is about $65 per set. If I was buying such a set I would be looking at the $70 and $72 sets. Or, perhaps buying rotors separately.

PPS Generally, if you purchase items with the Amex card then Amex will double the warranty on the item. Might be a good strategy if buying cheap rotors.

Snip of Rock Auto Alternatives:

 

All 2004-2009 Prius are considered Gen2. To the best of my recollection, all Gen2s use the same type of brake pads. Your Toyota parts guy can make sure that the Toyota part numbers listed in the link above work for your Gen2 (they should but does not hurt to confirm with an authority).

And search under 2008 Prius at Rock Auto to confirm part numbers there.

 

What's your current pad thickness?

Again, I would stick with Toyota. Considering you're more'n likely only doing this once in the car's lifetime. Have a read through the attachment I posted above. Do disconnect the 12 volt negative cable before commencing, then after everything's done, and before reconnecting the cable, pump the brake pedal multiple times, take up any pedal excess travel. The link show Toyota pads, shim kit and fitting kit (the second and third items may or may not be needed, but it doesn't hurt):

See posts #1 and #5 at: Which Gen2 Toyota Brake Pads Are the Right Ones? | PriusChat

A couple months ago genuine Toyota brake pads were $38 (from the particular dealer cited) for that particular part number. IIRC, the most expensive Toyota brake pads (cited in that link) were over $100 (and made in Japan). While cheapest were $38 (read the thread to get all the details).

 

Still $38 (plus S&H) at Bommarito Toyota. See:
