Repairing the Front Brake and Derailleur -- Part 1 (starting disassembly)

The front Brake is sticking (won't release once applied) and the front derailleur don't shift).  The LH brake lever/shifter is pretty damaged from several crashes.

The metal cap in the front is pretty dented up.  This picture shows the shift cable housing coming out of side of the assembly.

This is a picture of the brake cable as it enters the top of the front brake.  Nothing obviously wrong...

This picture shows the front brake cable housing routing from the front brake to the handlebar (it goes under the bar tape).  This cable housing is gray (original to the bike).  The shifter cable housings are white because I had Freddy (local bike shop) replace the shifter cables for me several years ago.  I brought him the cables and housing to use.

Folding back the lever hood reveals the bar tape and some soft gel padding material.

Took off the old bar tape.  It was worn in the area near the brake lever so it will be replaced.  There's some very squishy gel like material that's applied to the handle bars in strategic locations to cushion the hands.  These work very well & I'm going to reuse them.

To release the clamp that holds the brake lever assembly to the handlebar, you insert the Allen wrench along the side of the assembly, behind the hood.

There's rust on the brake lever assembly clamp.  The sea air is attacking all the components that can corrode...

Took off the gel padding (& the bar end cap).

Only the lever assembly needs to be removed now...

Used Dura Ace Brake Levers for the Cannondale from JW -- Will use the LH lever

JW used to have a bike with the same groupset.  After crashing, he replaced the damaged/scratched levers.  He gave me his left over damaged lever assemblies.  I've had these for about a year and am finally going to use some of it.

There's two RH and one LH levers in the box with a bunch of left over cable housings.

The one in the middle is the LH lever.  It's the least damaged.  The scratches/scuffing is pretty minor.

The RH levers are a little more damaged.

One of the RH levers.

This RH lever is the most damaged.

This is the LH lever that I'm going to use.  The closeup picture makes it look worse than it is...

Personal Emerson Fittipaldi Steering wheel -- Part 2 (cleaning & asassembly)

First, Cleaned the leather

There's some white spots in the leather that didn't come off with the cleaner.  Using a sharp blade, crape off the white spots very carefully...


After scraping off the white spots...

Apply black leather cream on the leather (dries dull)

The black leather cream is basically dry.  Next, using a clean cloth, buff the leather to remove excess leather cream and the bring out the shine of the leather surface.


After all the treatment, the white spot areas are no longer noticeable.

Put the hub back on with the cleaned fasteners & reinstall the cleaned horn button.

Turned out pretty nice in the end.  It's nice enough to go on a car now... (the guy I bought it from said that he used to have it on a VW GTI)
