hey guys. sorry if this is the wrong forum to be posting this in... but i figured id get more educated responses here

i have a wilwood front brake kit on my civic. it has the 4 pot dynalite calipers, which i believe do not have dust seals.

anyway, ive had these brakes on my car for almost a year. i have done about 4-5 hpdes with them. ive changed pads 3 times, and rotors once.

im about to get on the track again, and its time to change pads... but in the time ive had these brakes, i havent done any REAL maintenance on the calipers (besides cleaning the off/spraying them out). and theyve been used and abused on the track.

is there any maintenance i should be doing on a regular basis? any parts of the calipers that i might need to replace? i feel that i should replace the pins that hold the pads in, as you have to bend/rebend them each time you change pads.

any ideas/help is greatly appreciated.

 

Are you having any problems with the brake system? How is the pad wear? Is it even? Are they hanging or dragging? According to Wilwood they don't need any servicing, unless you notice a deteriation in performance.

If you still feel un easy, you can remove the pistons and clean them up and replace the o-rings. Which is a very cheap thing to due, just takes some time.

 

i havent noticed any deterioration in performance. the pad wear does seem quite even.

i assumed after such use, the calipers would require some attention. if not, then great!

 

i used to saftey wire in the pads instead of using that cotter pin.

 

thats actually a pretty good idea.

i seem to go through pads quick enough that it would a pain in the *** though.

i feel pretty comfortable with the safety factor, since the rest of brake system is safety wired.

 

Do your pistons sometimes sitck when you swap new, thicker pads for the older thin ones? Mine seem to do that all the time. I think pushing the pistons back in (after cleaning them, even) can put them at a funny angle and pedal feel and performance go right to the *******.

For pad retention, buy the Wilwood C-Clips and use those instead of the **** *** cotter pins. Makes pad changes even quicker and it lasts much longer.

 

I just finished changing the O-Rings and cleaning the pistons on mine. Just like someone said, cheap but it takes some time (couple of hours). I have had them for about a year now, and they only satrted giving me trouble for the first time barely a couple of weeks ago.

Here's what happened: you know those allen screws on the inside of the caliper, well they somehow got pretty loose, and it started leaking brake fluid (NOT GOOD) every time the pistons cmopressed. I gotta call Brain at Fastbrakes to let him know and ask him if there is a specific torque that they should have but it still seems weird since Ive never touched those screws. Must be the vibrations and a whole year of Time Trials and Track Days I guess. Just to let you guys know, so you can keep and eye on that and not go through what I had to go through. Oh yeah, besides that the calipers have performed really well, a whole year of abuse with no rebuilding and only now changing the O-Rings is pretty damn good.
