Wunderladen Civic Si/Integra F&R Solid Brake Caliper Bushings
Despite having seperate links, the front and rears are the same parts.
Link: Rear Brake Bushings
Link: Front Brake Bushing
Tools:
Ordered both F&R from Wunderladen which arrived quickly. When I opened the box, both sets were not labeled. Inspecting the bushings and hardware, I could not find any difference. Fearing they sent me two sets of rears or fronts I contacted Wunderladen and they responded "no worries, the front and rear bushings are the same". This is useful if you find either the front or rear is out of stock or if either is one is on sale, you can just order two of the same set.
Installation: Easy but messy.
After removing the sliding pins, you only need to partially slide the caliper over to push the rubber bushing out and slide the new bushing in. Use lots of brake grease to cover the whole bushing and sliding pin to aid install, protection, and performance.
Install Hiccups: 1 of 8 pins did not slide well but after adding more grease it was perfect. Pushing the pin past the oring inside the bushing can be difficult, it is a tight fit. Use a snap ring tool on the backside to keep the bushing in (I hate snap rings!!!). 1 of 8 bushings would not slide into the caliper hole, fixed by doing a single pass with a dremel with a fine sanding drum to clean the inside caliper bushing hole of oxidation and burs. The rubber weatherproofing caps are a tight fit so use grease to help them slide on.
Driving impressions:
I can't notice a difference. I tried various types of braking situations (heavy, light, trailing, pulsing, initial bite and release) but the brakes performed exactly the same, the pedal felt the same, no change in nvh, or noise. There is no driving upsides but there's also no downsides (except for my bank account having less money).
What it does fix:
The outside rear pads wear at an angle with the oem rubber bushings. The rear bushings mount towards the outside of the caliper which allows a twisting affect when the caliper squeezes the rotor. Solid bushing do not allow this to occur, keeping the pads parallel to the rotor. The front pads do not experience this "twist", since the caliper pins are more center-aligned with the pads.
Conclusion:
Driving: Not noticeable.
Maintenance: Keeps rear pad wear parallel to rotor. I also contacted Wunderladen about how long these are expected to last. They responded with, "Because of the rubber oring inside and the rubber cap outside sealing it from the weather, they only need to be regreased when replacing the pads and they should last the lifetime of the car."
Value: Well designed (except I hate snap rings!), machined to tight tolerances, and made of pricey brass. Since these don't make a performance difference except for preventing angled rear pads, I suggest skipping the fronts. A little expensive, I would have felt slightly better about the price had they came with packets of brake grease.
