1977 400F2 first restore project
AndyD:
Hi,
Likewise I love the impact wrench for stubborn fixings.
Have an air one but not too convenient when working in the shed away from the garage so splashed out on an 18v DeWalt one and it's a beast.
Love using it but definitely not for smaller fixings or screws - found a 10v cordless impact driver pretty good for these and much less violent.
Important issue with the wrench is taking care and wearing gloves, glasses etc. as it will happily rip things loose and spin them or distribute loose bits.
Cheers,
Andy

Again short on time today but a quick update. Found that the lower brake pipe was indeed blocked. Soaked in hot water and pushed a guitar string through and hey presto it's cleared. It's drying out on the radiator now. Will have time tomorrow to move forward with this. Meanwhile I am learning lot's about impact drivers, great stuff.

I love impact drivers brilliant tools in the right hands.
When the chippys at work get them out I cringe because they mash the heads or sheer them off screws and I have no chance of removing them after.

Front brake progress. Found that the upper brake line was also blocked, gave it the same treatment as the lower one to clear it out. Struggled to get fluid pumping down the lines and ended up using a technique from this site posted in 2009, using a syringe to pump fluid up which worked a treat. The brake worked but wasn't releasing its grip on the disc. Even got the brake light working. I know I shouldn't get so excited about that but it's early days. Next I squeezed on the brake lever and the brake pad started to move out and quickly the piston came out. The piston is badly corroded so I have ordered a new one with the seal.

Started cleaning the caliper and noticed some marks, sort of rivulets, under the paint and wondered if they were an issue, on removing the paint I don't think they are but have included an image if anyone has an opinion. Also included an image of the inside of the caliper and wondered if I should try to remove the hollow dowel to aid cleaning or is it best left in place. I gave it a bit of a tug with long nose pliers but it didn't want to yield. I think that its probably best left in place. New piston and seal arrived rapidly so is ready to fit once I have cleaned the caliper. Any recommendations on paint/prep welcome. Link to photos in previous post. Pretty much ready for a test ride once the front brake is sorted.
