So I'm planning to replace my front brake pads on an 01 s2000. When retracting the piston back into the caliper should I allow the fluid to get pushed backed to the MC, or out through a bleeder valve? I hate touching those bleeder valves, as each one I touch starts leading fluid between the threads. I usually just replace the the entire nippes, but in this case I don't want to wait for parts. Any opinions?

 

Do not open the bleeder.

 

Take some all purpose grease or vasoline and put it around the base of the bleeder screw. This will help with it leaking from around the threads and sucking air in.

 

I think I was misleading. I meant when I torque the screws back into place, they will seep fluid after the brake job. Happened to both my cbr f4i and sti. I would notice that the nipples were always wet after I replaced the brakes pads

 

That could just be fluid stuck in the the tip. that comes out ofter driving. Also as long as they aren't over torqued it should be ok. I rather have a tiny bit of fluid seep out that hurt the master cylinder. Maybe billman can chime in as he is the expert.

 

when replacing brake pads, it's not necessary to open the bleeder screw. open the lid of the master cylinder and push the piston back in. you can open the bleeder if you want. it won't hurt anything as long as you dont push and release the brake pedal with it open. releasing the brake pedal with the bleeder will allow air to enter the system. the caliper piston will be a bit easier to push it if the bleeder is open, but like i said, it's not necessary to open.

there should be no need to open the bleeder as stated ^ above. may i suggest this will be a good time to also flush you brake fluids?

 

I would let the fluids back into the reservoir. The fluid level goes down as the brake pads wear down.

If you have added brake fluids since the last pad change, I would use turkey baster to suck out some fluids so the reservoir does not spill over.

 

As long as you open the cap on the MC for the brakes, you'll be fine when retracting the piston. Depending on the amount of fluid you have in there, make sure you don't let the brake fluid overflow, and have a mess.

 

Perfect, thank you everybody!
