After moving the new to me Mark 2 closer to home, and experiencing total brake failure when unloading the not started sense 1985 Sedan. I have decided to just replace all of the Hydraulic parts, caliper’s, master cylinder, and hoses.
I was looking at using the Colbalt brand Brake Calipers, but on a Mark 2 are the Front and rear calipers the same parts? I can’t seem to find a definitive answer.
Hopefully your servo is working properly. Mine wasn’t on my 1959 Mark 1 and the cost to replace it was a pretty penny ! However, should you need to replace it, I recommend the unit from SNG as opposed to Moss’s. SNG’s unit is made in England while the Moss one is apparently made in India. the SNG one is more expensive for sure, but my pre-purchase research discovered that some of those who went with the Moss unit were sadly disappointed with the performance of this unit and said that , in retrospect, they just should have spent more money the first time rather than putting the Moss unit in, and then having to take it back out, then buying the SNG unit and putting that one in. As I said, hopefully you don’t need to replace the servo. Also, some of the units can be rebuilt by White Post Restoration, which is another alternative. Some parts may not available. Mine couldn’t be rebuilt.
Good Luck with your project !
Ok I finally decided to go with the Colbalt Brand Cylinders and pads, and as they came with no instructions I have a question, The original pads were retained to the Calipers by sliding them over the pin on the piston.
The new pistons do not have that pin, so do the pads just float between the piston and the disc? I have tried contacting the vendor with but have not received a response. Has anyone else here used this brand? They seem to also work on early E-types? Thanks
The pins are a ‘draw back’ feature, when the pedal is released a small washer acts on the pin to create a small gap to the rotor, I believe it was an attempt to stop premature wear of the pads, but willing to be corrected, when I had a piston corrode I turn a new one out of SS and just removed the pin, it worked fine. The pads are held in mechanically seperate from the pin.
