Re: [VintageLambo] Espada right front hub running hot- possible caliper sticking

Jack Riddell

Hi Shel, All the replies so far are worthy of consideration. I think Lars has defined the most probable cause - a caliper problem. Like he pointed out, the original pistons are chrome-plated steel and the chrome plating flakes off over time and can cause a seal to become less efficient. Like Fred pointed out, I just finished rebuilding my rear calipers last week as part of a project where I am restoring my entire rear suspension. You can order caliper rebuild kits and replacement pistons from GT Car Parts. The replacement pistons from GTCP are made of stainless steel - big improvement. FWIW, I have used DOT 5 fluid in my car for the better part of 15 years with no detrimental effect on seals. The DOT 5 is silicone-based and repels water (is "hydroscopic") so your system is not so susceptible to accumulating moisture and the corresponding problems it brings. Take a look at:http://www.geocities.com/lamboguy/Calipers.htmlThis is a short procedure I created when I rebuilt my front calipers. The rears are pretty similar except for the emergency brake components.

Is a rebuild kit avaiable for the caliper? Regards,Sheldon .
