914World.com _ 914World Garage _ RTV on Brakes

Posted by: Headrage Sep 18 2005, 06:45 PM

My car developed a loud squeal after I pulled the front pads off of the left side. When I pulled them I noticed that the pads were basically glued to the pistons with RTV.

Is it a common practice to do that???

I've used this liquid/goopy stuff on the back of brake pads that's used to stop squealing brake pads. Works pretty good, but if I remember right, you're supposed to let it dry before putting the pads back in. Sounds like someone put it on and stuck them back in, don't think that would hurt anything.

Scrap it off, pick some up at the FLAPS, and you're good to go. Oh yeah, it comes in different colors too. Color coordinate your brake pads, lol

Later, Don

Thanks Don...

I'll try the grease after I pull all of the crap out...

Remember that tube of orange stuff I handed you at that Pro Shop in San Pedro? I called it something like "Clown Splooge" ?

Buy that stuff. It's orange and like... $2.99 for a couple ounces. Apply to the back of your pads before reinstall. Be sure to let it dry.

In the olden days when I wuz yer age, we used elmer's glue on the back of the pads.
Just smear a thin layer across the pads about .020" or .030" thick and let it dry overnight.
next day install em and the pads will be nice and quiet.

RTV - I hadn't heard of that one, but I guess some guys will use it for anything

I typically just rub a thin coat of high-temp anti-seize on the pad backplate. Have tried other miracle compounds, stick-on gizmos etc. but they are basically worthless IME.

Dampening is what helps reduce pad squeal. Though there are a number of good products out there, I've used red RTV for years. It dampers very well. Those plastic shims provide a similar effect, thought they seem to not stay in place very well.

We used to use a blue "brake pad anti-squeal" that we called smurf spunk. It works great. FLAPS sells it in small packages that kinda look like ketchup packages.

FYI... all brakes squeal. The trick is to move the squeal to a range not audible to humans. I had a customer one time that kept complaining that his dog started howling everytime he hit the brakes in his pickup. I remembered about the squealing, so I replaced the brake pads and put the smurf spunk on them. No more dog howling.

The owner was amazed.

My '03 audi had RTV on the pads. I did not replace them that way and they vibrate just as the car comes to a stop.
