Prius (2004-09) :: 2005 - Rear Brakes Grabbing
Aug 7, 2011
About a year ago, the rear brakes became very suspectable to moisture and started grabbing. After a few stops the grabbing would subside, but I could still feel the rear brakes engaging a little earlier or more than the front brakes (the rear-end of the car would hunker down a little). So I replaced the rear shoes, the old ones had about 90K on them, not worn real bad and had plenty of life left. I made sure that when I installed them to clean everything, put a skim of silicone brake grease on a couple of the friction points and set the adjusters down so they would be able to auto adjust to the right setting.
The grabbing didn't stop, so I've lived with it for a while and finally got around to replacing the front brakes on the assumption that maybe since they were old that they may not be stopping the car as much as the new rear brakes were. Didn't work, in the back of my mind I'm wondering if there is possibly something wrong with the master cylinder and the balance between front and rear brakes is off. I'm going to go clean the rear brakes again today and crank the adjusters back to see if they adjust to a better position this time around. The drum and disc surfaces are in good shape and color.
Can the master cylinder get its balance messed up?

Two weeks ago I took my 2004 Prius (with about 165,000 miles on it) to the dealership because of problems with the rear (drum) brakes grabbing (sometimes hard enough to lockup one of the wheels). Their diagnosis was that they were badly out of adjustment. They "cleaned, adjusted and beveled rear brakes" which fixed the problem, but it returned this morning. I should also mention this dealership had "cleaned and adjusted" the rear brakes twice before over the last couple of years.

What causes grabing brakes in the morning OR when wet???

I have a 2007 Prius with 130,000 miles on it. I plan to trade in about a year, maybe a little less. I have noticed my brakes grabbing. My mechanic says that the front brakes are sort of grinding and the rear brakes are grabbing. Both are worn, the rear brakes to about 30%, front brakes to 60%. They also say they will probably last out the year. Should I put new brakes on to be safe and to be able to sell the car with new brakes, or should I just wait it out and trade it in with worn brakes?

I have an 2007 Toyota Prius and in the mornings, especially if it is humid or moist outside, my brakes grab badly during the first couple of stops....it's bad enough to make somebody run into the back of me. When it happens, you will also hear a screeching noise coming from the (sounds like ) rear brake, passenger side. I have taken the car to the local garage twice and they found nothing wrong. I have taken it to the local Toyota dealer 3 times and likewise, they found nothing wrong either.

So I have a 2012 Sonata with about 80k miles on it. I bought it used a few months ago. It has recently started having issues with the brakes.
When the car is cold and I start driving, every time I push down on the brakes they will do a quick grab after a few seconds. Sometimes its a slight grab and other times its a jerking grab. After I drive 10-20 miles or so and it warms up this goes away.

My 2005 Prius (86 K mi.) has a warning light on - brakes. Put on the scanner and came up with code P1116 coolant temp. sensor circuit stack for coolant heat storage system. Also C1378 - capacitor communication circuit malfunction. I'm just a shade tree mechanic but can usually fix stuff if I know where to start.

I just purchased this car & thought there may be a learning curve to dealing with the brakes, but I think it may be abnormal.
When braking, I apply more & more pressure smoothly down on the brakes, but no matter how evenly, slowly, and smoothly I try to remain when braking, there is a point when it abruptly brakes to jolt the passengers forward and make me look like a terrible driver, lol. It provides for a smooth decline in speed until I'm almost stopped, then it does it. Jerks us to a stop. So I've learned to apply even pressure and right before that is about to occur, lift up on the brakes and restart that slow pressure to avoid it happening.
I can deal with this because it's not that big of an inconvenience once I've gotten used to it, but I am just worried it may turn into something more or who knows, could be an easy fix. I had the car inspected by a Toyota dealership before I purchased it, and they said that everything was in great condition aside from windshield wipers. It has 81,000 miles, one owner, clean carfax.

I have a 2005 Toyota Camry that we purchased 14 months ago. When purchased it had bad brakes so the dealer replaced the rotors and calipers at their expense. A month ago I took the car in for a routine oil change and was notified that my rear calipers were stuck open and that my rear brakes were not working and rusted. The rotors look hardly worn, the one on the passenger side has some deep grooves in it and the driver side is pitted. We feel that we had poor work done when the brakes were replaced and that the back never worked. After the brake job was done we would get some "chinging" noise in the back brakes and I had them inspected twice and they said everything was fine. But now we find out they weren't fine.

My passenger side tail light (the upper part above the reverse lights) don't light up when you press on the break. Or rather, they light up, but just not as bright as the driver side. I took the car to the dealership and they told me they'd need to replace the entire tail light and I just wanted to see if that was indeed the case.

I've recently noticed that on my 2005 Gen 2, after starting the car, the first few miles I drive produce a gentle metallic rhythmic scraping sound coming from the right rear wheel.
It's only audible when driving at low speeds (<30 mph), and seems to disappear after the car has been driven for a few miles. But when I start the car fresh the next day, it has reappeared.
The rate of the scraping noise varies directly with the speed I'm driving. I think it only happens when I'm coasting (in Drive), and possibly also when I'm braking.
My guess is something is slightly misaligned or rusty - a disc brake? And the noise "disappears" when the metal gets warmed up?

I bought a used 2005 Prius in early February, and have driven about 7,000 miles so far.
Yesterday, I noticed an issue with the braking. When the traditional brakes (non-regenerative) kick in when approaching a full-stop the right-rear tire completely locks up, and skids. The weather has been wet the past two days, but the issue is severe enough that the resulting vibrations feel like they may tear the car apart.
There are no warning lights aside from the skid light, so I assume there'll be no code for a mechanic to easily identify this problem. I'm worried if it's not easy to pin down, this may be a huge expense, and if so, I'll have to hold off awhile, and find some other mode of transportation.

I just bought a 2005 Prius a couple days ago and have spent the weekend discovering "hidden" little issues. One was that after a heavy night a rain there was a small pool of water in the very back of the car underneath the cargo area near the wire that runs from the traction battery. In fact the little prongs holding a slim white (electronic) box connecting to the battery were rusted out.

I didn't need to replace the rear shoes. I just did it because the front brake pads were worn and I thought the rear shoes might be worn also. The front brakes were super easy to replace. The rear brakes not so easy. I ended up using a breaker bar and a 32mm axle socket wrench just to loosen the spindle/hub nut so I could remove the brake drum.
I re-assembled the brakes shoes and springs exactly like it shows in my Haynes manual. The new shoes are shaped identical to the ones I replaced. Now I can't get the shoes to seat tight when I apply the brakes and my parking brake isn't working at all, although I can see the parking brake lever move on the trailing shoe when the lever on the console in the car is raised and lowered.
I did as the manual directed. After putting the wheels back on, I applied the brakes "forcefully" a number of times while I was driving forward and backward. This was supposed to auto adjust the brakes. There is no adjuster slot. (The front brakes are stopping fine.)
The old shoes weren't that worn when I replaced them, so the parking brake shouldn't be totally out of adjustment. I don't want to remove the console and start messing with the parking brake cable adjustment until I can figure out what I must have done wrong when I worked on the rear brakes. It seems like the adjuster lever pawl is not working?

My car got into an accident and the driver side door needed to be replaced. My wife picked the car up from the shop, but i guess she did not think anything wrong with the car. My problem is as follows:
When I go to grab the handles of my car (driver, passenger, trunk) with my key fob in close proximity (pocket), instead of the double beep signalling an unlock of the doors, there are multiple beeps (maybe 5 sets of double beeps) along with the emergency flashers flashing.

I have a rough chatter noise coming from the rear end. It happens when starting off up till about 25mph. It rattles the cab a little and sounds real rough. It also happens when turning up hill, causes lots of vibrations in the cab. Some have mentioned it could be the rear differential needing a friction modifier or the u-joints needs some special lube? Its an 05 F150 with 62K miles.

I have a 1997 F150, 4X4. My mechanic says its time for new brakes and was curious if it would be worth possibly converting from drum brakes to disc brakes??
My mechanic has quoted me $300 to do the rear brakes, would it be worth the extra money to convert??? I really don't care for drum brakes. I have done a search on the internet and every time it brings up the issue with the parking brake.

So, my 2012 Prius has 61,000 miles and I started hearing some terrible squealing from my rear brakes. This weekend, I decided to take the tires off and investigate. Turns out, that my rear pads were worn to metal.
I switched the pads with new ones. The rotor was still new and didn't need replacing. Torqued the caliper bolt to 25ft/lb and put it back together. However at the end, I forgot to put back on the two wire clips take keep the brake pads apart!
Do I need to put these clips on? I'm too lazy to take my tires off again.
Lesson learned: Turn clockwise and PUSH the rear piston at the same time to get it to go back in. Turning it alone does nothing.

I brought my prius v back to the dealer for the fourth time because of the groaning noise from the rear brakes. I was told that Toyota is aware of the problem and they are designing a new rear brake. They expect it to be ready for installation after January 1st, 2013. Let's hope it isn't too far after the first of the year.

The uneven wear occurred again, this time only giving me 22,644 miles on the rear brakes. So, I am on my third set of rear brakes at 78,000 miles.
This time the dealer contacted the district rep since this was a repeat occurrence. It turns out a week after my first rear brake job, Toyota issued T-SB-0248-12, for this very problem, on the 2010 - 2012 Prius and on the 2012 Prius PHV. There is a new brake pad that is supposed to address this problem. The old part number that was put on my car during the first brake job was 04466-76011 and the new part number is 04466-47080. The receipt also shows Brake Shim Grease part number 08887-80409, which is noted in the TSB.
Toyota did the right thing in that they covered the cost of the brake job I just had done. I just opened a case asking to be reimbursed for the first brake job since this turned out to be a problem that was addressed with a new part.
I suggest anyone with a 2010-2012 Prius or 2012 Prius PHV that needs rear brakes, make sure you insist on getting this updated pad and point out this TSB. My service adviser said they were going to replace all of their pads with the old part number with the updated pad, so other customers going forward receive this new pad, though he also said they just don't do a lot of Prius brake jobs.
