Somebody mentioned in one forum using RTV silicone to patch it. I see a lot of confusion on this online (Autozone has yet another picture on their site) and folks say the manual says you can have problems if you get the pins in the wrong position.Ģ) What do you lube the pin with - can you use molybdenum caliper grease (safe for rubber gaskets) or should you use only silicone? Some folks say they wash the inside out with brake cleaner but I wondered about getting that on the rubber boot? And if only silicone is allowed, what type/brand/model do you recommend for the caliper?ģ) What do you torque it to when done - is it 25lbft or 36 lb ft? I see both mentioned on different pics?Ĥ) I notice my piston gasket is slightly damaged. But the following picture shows the reverse arrangement for a 2006 CR-V? Which is it (specifically for a 2004).ġ) For my 2004 CR-V, does anyone know if the fluted pin goes on the top or bottom for the front brake setup- a picture would be great. This 2005 pic above shows the 3-fluted caliper pin in the bottom slot and the pin with black rubber tip ring in the top slot. I'm confused by this picture above and the following one on a second post. Hard to distinguish in writing, but a real time example is more illuminating.Hi, I have a question/clarification on this discussion for the front brake caliper pins on a 2004 CR-V: A front hang-up can do this as well, but not to the same extent. A rear axle issue will manifest itself not at the start of the brake application in the steering wheel, but become more prevalent at the end of the stop, drifting the vehicle to one side. While we call the front axle pull a "pull", a rear axle pull is known as a "drift". Which Brake Caliper Guide Pin Goes on Top To address unusual noises or vibrations that occur while braking They are similar in length and girth While one. Again, a switch of just the outer (or inner pads) from one side to the other often takes care of this issue.Īnother thing you should always check is if the pull is from the rear axle rather then the front. These vehicles are very sensitive to variation due to the scrub radius. If a pull has been an issue since new pads had been installed, it's also possible that there is some variation in the manufacture of the material leading to the imbalance. It's also a location I like to put a light coat of caliper silicone grease at, but not petroleum grease. Often just some light filing or sanding of the tabs clears up this issue. The pad should be free to move without any prying. And over time, rust also builds up on the tabs locking them in the bracket. It goes in until the last rubber 'ring' is flush with the rim of the hole. I cannot get the bottom pin to go back in completely. The bottom pin is metal with rubber 'rings on the outside. And in some cases I've also come across aftermarket steelbacks with excessive paint, which hangs up the tabs as well. On the front brakes, I removed the top and bottom brake caliper pins. A pad that is not freely moving in the bracket is just as bad as a hung up sliding pin.Īftermarket pad steelbacks are sourced from only two suppliers in the US, and their tolerance during stamping is not are tight as the OE standard. If this has happened, then the simple switch of one, or in some cases both pads, from one side of the vehicle to the other can make a difference.īut while your opening up the brakes, you should also check the fitment of the pads in the brackets on the pulling side.

Also, you should only use a NON-PETROLEUM base lube on the sliders (e.g. So if you have a dragging brake caliper, the pads on that side can become more effective then on the other side. Online shopping for Caliper Bolts & Pins - Calipers & Parts from a great selection at Automotive Store. The slider pins with the rubber bushing goes on the bottom position (front and rear). More heat exposure, more carbonization at the friction interface, and generally a higher effectiveness. But a characteristic of any metallic is that it will alter its coefficient of friction dependent on the heat history. Before you get too nuts spending money on replacing parts, try to switch the outer pads left to right side.Īll of the brake pads supplied for these vehicles are a semi-metallic. Once Id eliminated the park brake I tracked it down to sticky slide/guide pins - sort of sticky in a rubbery sort of way.
