DIY : Honda Civic 1987-2000 Front Brake Calipers/Pistons Maintenance/rebuild

Posted in My Automotive Life | No Comments »

Well…safety is always the first, this is the part and mechanism that make sure your life is under safety term when you drive your machine, but you also need to make sure this mechanism is safety to use, especially when the mileages is beyond 100 000km, inspection is crucial…

DISCLAIMER: I can not say this is the best or safest way to do. I am not
responsible for any thing you damage, or what ever harm you cause to
yourself or others. This is how I did it and it worked for me.

Remove the banjo bolt and disconnect the brake hose from caliper, don’t worry about brake fluid, after sometime brake fluid will stop flowing. It’s a good idea to have something to catch the excess brake fluid that will drain from the lines. For example, half of empty mineral bottle.

Remove the two caliper mounting bolts and the caliper bracket bolts (if you want to service and paint your caliper bracket).

Wow! 

Apply compressed air to the caliper fluid inlet to get the piston out, be-careful, make sure your fingers in safety place. For cushioning, place wooden piece or rag in front of piston.

Inspection…

Result : Need to replace the piston, piston seal and piston boot.

Comparison between old and new piston, piston seal and piston boot.

Clean the cylinder groove and all parts as clean as you can!

Painting time!

Install the new piston seal.

This is the tricky part, to install piston with the piston boot in the cylinder. Firstly, install the boot onto the piston with the correct position.

Next, hmm, the picture will tell you more…

Slightly and slowly insert the outer boot lip in the cylinder groove, corner by corner using fingers and a small flat-head screwdriver (be-careful, you may tear the boot) .

Yeah, passion is need here…

Done!

Make sure the boot in the right place.

Reassembly all back together using reverse step, re-grease the caliper pin and install the new brake pads.

Hmm, satisfy enough…

Make the bleeding proces. Now, it’s time to rolling again!
