Front Caliper rebuild

Well, I think my front caliper is due for a rebuild.

Abnormal wear, and squealing this last ride.

Looks like one of the pistons might have seized up.

Anyone know of somewhere on line to get some good instructions on doing the rebuild myself?

Thanks in advance.


calipers are not that hard to rebuild. you'll need the seals for sure and maybe new pistons if they are pitted, scored or badly corroded.

1) take caliper off of the bike, detaching the brake line

2) empty all the fluid that you can

(ALT) pull the caliper off its mount and squeeze the brake lever till the pistons pop out.....MESSY

3) place a piece of wood on the side of the caliper opposite the pistons

4) use an air compressor and blow gun in the brake line hole to force the pistons out of their bore......start slow on this

5) if the pistons are in good shape, you can lightly polish them and reuse...if there is anything that wont come off with a light polish, replace them...better safe than sorry

6) take off the old seals

7) dip the new seals and pistons in brake fluid...

8) install seals in bore

9) install pistons

10) clean caliper

11) put caliper back on bike

12) attach brake line

that should get you through it. if anyone knows any other tricks please add them

      Hey I have a crf250x 2005 I was riding today in top gear flat out and when I slowed down blue smoke just poured out the exsaughst then I happened to open the air box lid and saw it has what looked like engine oil in it then took out air filter and noticed that there was splatters of engine oil on the inside and that and the channel that goes to the carby had engine oil all over it.
      Also bike got a top end rebuild 15 hours ago
      The engine still runs good and sounds normal
      why would this be happening on a resonabley fresh engine

      Hey everybody. Quick question for y'all. I recently went riding and about halfway through my ride my motor seized on my '07 CRF250X. I haven't investigated it much but I checked the oil when I got home and there basically was none so I'm assuming that was the culprit. There weren't any metal shavings in the filter or on the plug either. At this point I'm trying to decide to rebuild the motor or just sell the bike as is and let the next buyer deal with it (they would know the deal obviously.) I feel that I'm pretty mechanically inclined but rebuilding a CRF engine is a bit out of my league and I assume paying a shop to do it would put me out more money than the bike is worth. So, I have this question to ask; what would be a fair price for a pretty dang nice shape 07 CRF250X, with a seized motor with an unknown extent of internal damage?

      I have two rides in on my new Rekluse auto clutch and I have to say I'm very pleased. The install wasn't hard, but was pretty much a all afternoon sort of project. I also installed a left hand rear brake kit and a two finger cluth over-ride with the adjuster on the perch (which I rarely seem to need). It has all worked great right from the beginning. After struggling to get up a tricky hill in first gear, I tried it in second and the autoclutch helped me clean the hill easily. Not having to worry about clutch action in techinical sessions has also eased fatigue and just made it more fun all the way around. I ride mountain bikes alot, and having both brakes up on the bars has also been nice as it makes for a set-up just like the bicycle - in fact I like that as much as not having to worry about clutch manipulation. The brake on the bar is especially nice on tricky downhill sections where you need to paddle, such as nasty rock/rut stuff. So first impressions are that it was worth the investment -making the ride more enjoyable and easier at the same time!

      I was driving the bike for 15min or so and all of the sudden the bike stalled. I tried starting it again with no luck. I took the spark plug out to see if there is spark so i ground the spark plug to the frame and there is no spark. I even put a new spark plug in the bike and still nothing. Any ideas what i should check??
