Do I need to replace caliper bolts?

This all means that the brake caliper bracket, the bit that bolts to the knuckle on the front and the rear, should have new bolts when you replace the disc rotors. If only replacing pads, the small bolts holding the sliding caliper to the bracket, can be cleaned with a wire brush, add a drop of loctite, and reuse.

How tight should caliper bolts be?

Because caliper bolts MUST stay on, they need a LOT of torque. AutoZone, for example, recommends 113 pound feet of torque. To put that number in perspective, the average person can ( according to NASA) apply about 15 pound feet with a bare hand.

Are caliper bolts one time use?

too. jcthorne said: Just FYI, the 2006 service manual also instructs that the caliper bolts are one time use.

Do you grease caliper bolts?

Before putting the caliper bolts back into their spot, they need to be lubricated properly. Brakes are one of the hottest places for your car, so you’re going to need high-temperature grease. This lubricant is synthetic and can withstand the high temperatures that your car’s brakes will reach.

Can I use anti seize on brake caliper bolts?

Registered. Anti seize is no good for slide pins, it tends to solidify and not do its job very well for what it needs to to. I use a dab of blue loctite on the bracket bolts and a leave the caliper bolt threads dry. Never had an issue with those seizing, even in PA.

Do I need to bleed brakes after changing caliper?

If you have a 3 channel ABS system, either of your front calipers will be OK to bleed independently, but if you are working on any one of the rear calipers (or cylinders), you’ll need to bleed both of them. You get the idea. You’ll have to bleed whichever brake calipers (or cylinders) are on the same line.

Are brake caliper bolts universal?

Since all brake calipers are unique to each manufacturer, and often made from different materials, there is no universal torque pressure setting for brake calipers. Even they make mistakes when it comes to installing brake caliper bolts.

Do you put grease on caliper bolts?

2. Not lubricating the guide pins: Caliper guide pins on floating calipers should be cleaned in solvent and new grease should be applied. The grease is under extreme heat and pressure so always use a caliper specific grease. NEVER put a torn boot back on a car.

What is a bad brake caliper?

Inspect the brake pads. If the brake pads are showing signs of early wear, then it could be a sign of a bad caliper. This would mean the the caliper is not fully compressing inside of the caliper housing and the brake pads are dragging against the brake rotor as the vehicle is driving down the road.

Does the brake caliper suppose to be loose?

Your caliper shouldnt be loose at all. When your pads wear the moving part of the caliper slides in to keep all that tight and the piston stays out and keeps the back pad close to the rotor. You need to look at the the caliper bolts on the back and also look at the cariage bolts. How do you tell if a caliper is seized?

What are brake caliper pistons made of?

The brake caliper is the assembly which houses the brake pads and pistons. The pistons are usually made of aluminum, chrome plated steel, or from a composite material called phenolic.

What is the thickness of a brake caliper?

The minimum allowed thickness for the brakes pads is 2 mm. However, Porsche generally recommends replacing the brake pads at a thickness of 2.5 mm. If the brake pads are replaced at 2mm or the wear indicators have been activated, the wear indicators must be replaced along with the brake pads.
