My 2013 Camry has 168K miles on it and I'm doing a complete brake job on it including rotors, pads and calipers. I know a lot of the foreign cars have these Torque to Yield bolts on them and now, from what I hear, GM and Ford trucks have them. To my understanding these are one- time bolts and must use new ones. My question is does the 2013 have these bolts on any part of brake systems I'll be replacing and if so what is the torque and degrees on these bolts? Also, if so, is there a particular torque wrench to use on these? These maybe just a recent technology thing but just being cautious. Don't want any surprises.

 

Torque to yield bolts are used for cylinder head bolts where a uniform clamping force is needed. Never heard of these kinds of bolts being used on the Toyota brake system.

To install this kind of bolt, one torque's the bolt to a set spec. Once done the bolt is then rotated a specified number of degrees. There is mechanical degree tool which attaches between the socket and wrench that is used to measure the degree of rotation. The tools are low cost and readily available.

Search under "torque to yield angle gauge."

 

Thanks for your reply. I'll probably just have to find a good repair manual, an online digital download if there is a good site to see the complete brake system removal and repair. First time i've ever had to do any work like this on the car. The Torque to yield bolts are making their way into other automotive assemblies besides the engine. They are being used in rear axle and wheel assemblies. Don't know how long. I recently watched a video of this on Royalty Auto Service on these asemblies and that these bolts are disposable. Not to be reused at second time. Installed the first time to torque, in the second turn for the angle, the bolt is stretched and if used again it could break. In the case of a rear axle failure it could cause the axle to come apart while driving down the highway. The examle used on the show was on a wheel assembly. But I could not tell if it was the rotor or other part of the wheel assembly. It was from behind. Was not a Toyota. I hate it that automotive maufacturers are going the cheap way out of doing things.

 

YouTube can have decent videos of Toyota repairs.

All bolts stretch when put under tension. The issue is if the bolt returns to its original length after the tension is released. A bolt which has been tensioned to much will stretch and stay stretched.

Lots of opinions if these bolts can be reused. Some say yes, some say no.

These bolts are typically cheap to buy thus replacing them is not a cost concern.
