Repai of the brake system started (My original blog was written on 17th Dec. 2007)

I moved to the 2nd step to revive my onboro ALFA!


Today I jacked up my car to start the maintenance of the brakes and suspensions.

It took little time to raise the car to the height level of the jack stands because the lift up of my garage jack was not in good condition.  However, I could start the check.



At first I tried to remove the wheels, but as I expected the wheel nuts were sticking.
10 years slept wheel nuts were very tough enough.  But I managed to loosen them with the chemical Rus-pene.

I met with the brake calipers, brake master cylinder and clutch master cylinders after a long time.



The calipers were ATE, the brake master cylinder was BONARDI and the clutch master cylinder was BENDITALIA.
All of them were in a bad condition … I had to overhaul.

I would do my best to make them beautiful!

Tip to repair rubber parts

I disassembled the rear axle before.  There had been no progress on it because I started the repair of the fuel tank during my summer holiday. While painting the fuel tank , I repaired the torn rubber boot of the parking brake wire. I guessed it didn ’ t cost high because it was small rubber part.  But I wanted to try the repair method I read on the magazine article before. This was the condition before the repair.  The rubber was torn apart and separated almost. I used this self-adhesive type butyl tape.  I pasted lots of small pieces of the butyl tape on the back side of the rubber boot.  As time goes by , these tapes would melt and stick together.  After this I applied plenty of adhesive “ Super X Black ” on the rubber boot.  On the magazine of MOTO MAINTENANCE , I read the article that the motorcycle seat was repaired with this method.  So , I wanted to try it. After drying 1 day , it became like this....

Clutch master cylinder overhaul #3

I was still struggling with the sticking piston of the clutch master cylinder. I thought I should give up and look for the new part for the replacement.  And to for my curiosity , I started to destroy and disassemble the clutch master cylinder piston by drilling. When I was drilling the piston halfway , I didn ’ t have any specific idea , however , I thought to tap the piston to make the thread.  I started to turn the tap handle , and I felt the feeling that the piston was moved.  So , I tried to pull it , and then suddenly the piston was removed from the cylinder. Finally I could extract the rusty piston! I observed the extracted piston.  It looked there was no risk of the leakage of the fluid because the hole I made in the piston was not penetrated.  Thinking the function that this part only holding the rod connected with the clutch pedal , it could be reused if the hole would be filled by the hard material. However , be...

Clutch master cylinder overhaul #2: tough match

I disassembled the removed clutch master cylinder. And I found that the piston was heavily rusted. I tried to hit it with a hummer , Pushed the piston using the vise clamp like this.  However , the piston was heavily sticking by rust and it could not to be moved today. The brake master cylinder was replaced in the past , however , the clutch master cylinder was not.  Therefore , the condition of the clutch master cylinder might be worse. Tentatively , I would spray the rust-penetration lubricant from both sides of the piston and try again in a few days. If it doesn ’ t work , I would give up the overhaul and order the new part.
