Damaged Caliper bolt threads

[hkazmi]

Hi Guys, I have 2010 4Runner limited, 2010, my mechanic told me that the bolts on my rear calipers were ceased so bad that it end up tearing the threads when they were opened. He is recommending replacing them?

On one side, the thread on the floating bolt is torn, on the other the frame that holds the break shoe and caliper is torn,

I am a little disappointed as calipers themselves are working fine, I am also thinking of now fixing it myself as he is quoting a lot of dough to fix it. Firstly he is insisting I by from him and he is selling me re-manufactured calipers for twice of what is available in the market, second the labor is quite high, all in all I can do it for 1/5th the price myself. I have done this on a 15+ year old car and it wasn't too bad.

Yet I am not a mechanic, so the question? What the hell is this thing which holds the break shoes (and calipers) called?

any other recommendations? I looked into heli-coils, but re-threading tools will cost me half the cost of replacement calipers!

Having not seen any of the parts - it's pretty odd that that happened. Why was he removing the rear calipers?

Second - it's common that the threads could be re-cut without helicoils. Just running either a thread chaser or a tap through the flange. It depends on how the threads look internally. I'm not a fan of the aluminum coating on Toyota's new hardware. It constantly ruins the threads. I would look at them and if you can cut it with a tap so you have about 8 or more good clean threads, it's probably good enough.

We were replacing the rotors, I am guessing living in Canada means lots of so salt on the roads caused all sorts of rust and jammed bolts.

In the mean time, goolge let me know, its called a bracket

I would replace the calipers myself. Brake work is pretty easy(assuming no seized bolts) and it is marked up ridiculously at shops. It sounds like you're not afraid so go for it

Garage has already taken care of seized bolts by tearing up the threads :car:

Replacing the brackets is easy man. You should be able to handle it yourself its very straight forward. Save some $$ for the mods

Two separate issues here:

1) The calipers attach to plates that are part of the axle. Two bolts each go through the plates and thread into the calipers.

2) Calipers themselves have two threaded pins that screw into the floating part of the caliper. These get special silicon grease that comes with the pads.

I don't understand you use of the term "torn". Hard to imagine bolts or brake calipers being torn.

You can get new AC Delco Calipers for $60 on Rock Auto. AC Delco is quality stuff.

I just did rear pads and rotors on my wife's SR5 and it took me a little over an hour. She has 144K miles on the vehicle which was purchased in September 2014. Rotors had a lip on them, so I put new ones on. Last changed the pads at 75K miles.

heli coil

I am warming up to helicoil, does anyone know the thread size of floating pins on rear calipers?
