Front Brake Pad/Rotor Replacement

It may very well upset the car's electronics, trigger warnings. Consider disconnecting the 12 volt before swinging the caliper away from the disk, and avoid opening the driver's door. Have you noticed the whir sound pretty much whenever you open drivers door: that could eject a piston if the caliper's swung up.

I'm scared off brake jobs on this car, but other brave souls have done pad replacement I think.

 

Does anyone have the procedure or manual pages for doing a brake job on a Prius Gen 3?

 

what is that whirring sound?

subscribed . i was wondering how difficult this was as well

 

My hunch is opening the bleeder valve will cause an issue. That the electronics will detect an intitial low pressure at boot-up. Maybe push back the piston but leave the bleeder alone?'

Still, with all the electronics (and I've done pad replacements for decades) I'm inclined to just pass it to the pros.

 

The sound is the brake system building up pressure. Since the ICE doesn't run all the time to build up vacuum, it has an accumulator for pressure.

 

Awesome . Thank you .

Now back to trying to change the brakes .

 

you shouldn't need to open the bleeder to pish the piston in. jist wait a while till the accumulated pressure has blead off.

 

I have not done this on the Prius...yet...however the first step says to "Disable Brake Control". You will not need to open the bleeder. just remove the bolts, do a little wiggle and slide the caliper up and away. A "C-Clamp is best for compressing the shoe/piston, and is needed for clearance to install with the thicker new pads.

The manual does state this:

When the brake pedal is first depressed after replacing the brake pads or pushing back the disc
brake piston, DTC C1214 may be output. As there is no malfunction, clear the DTC.

So you will need to be able to clear the code likely thrown.

Still looking for definition of "Disable Brake Control". Though the battery and door trick may be acceptable, I would make sure first so you do not disable the car and have to bend over at the Dealership afterwards.

Will post more later if some one does not beat me to it. Going to work now.

 

That was on the 2010 Prius? Except you didn't crack the bleed bolt?

Good to know.

 

so it sounds like a pretty standard brake job except you have to disconnect the battery , keep the fob in the house and lock the car with the key lol

 

I have been searching the web to see if there is any video showing how brake pad replacement is done on any generation of prius (2000-2013) and I have not found a single video. Prius is a rare breed

 

I just had the front brakes apart last night. Disconnected the 12v first, then removed the caliper and bracket. Caliper bolts are a 14mm and the bracket bolts are a 17mm. You may need to a flathead screwdriver to pry against the end of the caliper pins to keep them from spinning.

Be sure to lube the slide pins with fresh silicone lube. My brakes still had 4.5mm left after 77k, but the slide pins were frozen in the bracket.

Pump the pedal 10-15 times before reconnecting the battery and you should not set any codes.

 

Anybody have a schematic of the brake assembly? Or point me to one?

 

There are quite a few people now, including me, who have actually disassembled, serviced and/or replaced brakes on their 2010+ Prius without setting codes, etc., by: first disconnecting the 12V battery, leaving the driver's door shut, and lastly pumping the brake pedal when finished to restore firmness before reconnecting the 12V battery. Just don't try to flush or bleed the system yourself; leave that for the dealer.

Lubricating the slide pins is essential to keep the calipers from seizing and causing major repair expense.

 

I found this for the rear brakes: Toyota Prius Rear Disc Brake Pads Replacement Guide - Gen III 2010 To 2013 Model Years - Picture Illustrated Automotive Maintenance DIY Instructions

Are the front brakes different than the rear or is the procedure the same?

Also it says not to compress the piston with a clamp. The piston uses a disc brake piston tool.

 

Front brakes would actually be easier. The piston can be pyshed in with a clamp and they don't have the springs the rear has.

 

Hoped you would chimed in.
