Even before taking apart the clutch cylinders<\/a> I knew I needed (and wanted) to change them for new parts. And today they arrived from the mail. But with a small twist:<\/p>\n\n\n\n

Peugeot 504 wrong style of brake and clutch cylinders<\/figcaption><\/figure>\n\n\n\n

Fortunately the seller agreed to exchange them, so I repackaged the wrong parts (because the hoses and the other pump were the right ones) and dropped the box at the mail.<\/p>\n\n\n\n

I’m amazed that even with that hiccup it was cheaper to order them from a parts store at the other corner of the province than buying locally.<\/p>\n\n\n\n

Just for kicks I wanted to see what’s inside the brake master cylinder but it was really really stuck.<\/p>\n\n\n\n

First I enlarged the recess on the piston a bit and used a half inch tap to try and grab it. It turned slightly but then the threads snapped.<\/p>\n\n\n\n

My curiosity called for extreme measures and I conjured the power of the air to aid me.<\/p>\n\n\n\n

Rummaging through the jar of pipe fittings I found a combination that allowed me to connect the cylinder to the pistol I use to pump the tires.<\/p>\n\n\n\n

I gently increased the pressure until the innards flew across the table. This was sketchy and unsafe as fuck. Think of a potato cannon but throwing a chunk of metal.<\/p>\n\n\n\n

The pistons were more or less acceptable save for rubber and dirt deposits. But some of the seals almost disintegrated when touched.<\/p>\n\n\n\n
