Aston Martin Vanquish Manual : Slave Cylinder Teardown & Master Cylinder Selection. Modurol MT45

In this video, we dive deep into the hydraulics of the Aston Martin Vanquish (2001-2009) manual transmission conversion. We take apart the Valeo 110236 slave cylinder to understand its internals and measure the piston dimensions—critical data for specifying the perfect master cylinder.

Using an AI-assisted engineering evaluation report, we compare three options for the master cylinder bore:
3/4" (Traditional/Soft): Light effort, but potentially too much travel.
13/16" (The GT Sweet Spot): Our top recommendation for a refined, modern pedal feel.
7/8" (Performance/Race): Ultra-fast engagement, but trickier in stop-and-go traffic.

We also discuss why 3/16" stainless steel hard lines are a must for maintaining 100% hydraulic efficiency and avoiding the "spongy" feel of hose expansion.

What we cover:
0:00 - Introduction to the Valeo 110236 Slave
0:57 - Teardown: Removing the spring clip and bearing
1:58 - Extracting the piston with compressed air
2:30 - Measuring the piston size and stroke
2:48 - Engineering Report: Comparing Master Cylinder options
5:33 - The Final Recommendation: Why 13/16" is king for the V12
8:33 - Tech Tip: Hard lines vs. Braided hoses
8:40 - Wrap up
