Scoring on rotors

Hummm, I've read very similar thread recently. Is this going to be a recurring problem with Gen4 OEM rotor?

Also check this post - she managed to get TOYOTA to replace hers:

Brakes already!?!? | PriusChat

 

Disconnect 12 volt negative before starting, and when done, before reconnecting, pump brake pedal a few times to take out any excess travel.

When pushing in the pads use something (old brake pad, plywood, steel plate) to spread the load evenly over the piston rim: it's some high-tech plastic, can crack.

Only rear brakes are screw-in caliper pistons, due to integrated parking brake. Do be careful with orientattion of that piston. It's imperative to have piston orientation per pic in Repair Manual, so pin on back of brake pad fits between "spokes" on the piston face (see attached).

 

I think you probably are about to waste a LOT of time and money.
Some "rippling" of the rotors is quite normal and depends mostly on the construction of the pads used.
Deep gouges, of course, are not normal.
But it seems like a LOT of people can't tell the difference.

Have you ever done a complete brake job on a system with ABS and traction control before ?
The fluid probably should be replaced too while you are at it.

 

I listen. I’m the guy who listens. Would this issue make a noise when braking, esp slowing down to a stop? Mine has been making a clicking sound from 20 - 0 mph. I can hear this when the drivers side window is down, sounds like the front axle. I had not thought about the brakes. But will ask my Toyota advisor next service

 

"Clicking" does not normally come from the brakes.
More likely that there is a big rock in the tire tread.......or a nail stuck in one.
Might NOT want to wait for the next scheduled service to check it out.

 

Thank you

 

Don't know if any of the Prius models have "real" hubcaps or not......but a rock stuck behind a hubcap can do that too.

 

Again thanks. I’ll look at both suggestions.

My 4 touring has 17” alloys w partial wheel covers. Weird design.

 

Tucatz that clicking noise is the front axle. I had mine in the shop 7 times before they listen and replaced the driver's side axle. It cause low speed clicking. On mine the noise would stop for a day or two every time it was lifted which made finding it a challenge. You can also find others here who have had the same clicking issues at low speed.

Are you talking Gen 4 or Prius c?

 

They've really got to get in gear regarding this insane amount of salt dumped on the road. There are alternatives that are less harmful to cars, and the environment.

I think too, regulations are restricting metal coatings, the cars' suspensions, frames, all the bolts, are rusting like crazy. I find boiled linseed oil (brushed on) good for that.

 

Surprisingly cold on west coast right now too, -1 C right now. Yeah I know, shirt sleeve weather for you. I just can't take it. I did an oil change and tire rotation on our daughter's Pilot yesterday, and as usual she shows up around 4 PM, so I'm working as it really starts to get cool down and dark. Ugh.

 

Did it at least have oil in the sump.

But I’ll probably be in the same spot as my kids get old enough to drive.

Situational awareness is something not a lot have.

 

Yeah it was in decent shape, I've been keeping on it, topping it up. One tire was down to about zero pounds pressure though. The TPMS alerted, and showed which corner it was (this is a 2010). Can see the likely suspect (screw head showing in the tread, been there a while), chalk-marked the sidewall and left it in the tread, aired it up with (with bicycle pump) and made her promise to drop by Kal Tire for a kosher inside/outside plug repair. She's semi-diligent about that. I hope...
