RobinTR Posted October 28, 2020 Report Share Posted October 28, 2020 I suspect that the rear wheel arch mounted brackets can rot out from the inside, so was planning to remove, treat and replace the contact faces during my TR6 rebuild. However, the square shaped face is dished in, so please can someone advise if they started flat, but have dished as the result of repeated bump stop action, or if the originals did have concave faces?

RobinTR Posted October 28, 2020 Author Report Share Posted October 28, 2020 Thanks Stuart. Will check for corrosion and only repair if necessary Quote Link to post Share on other sites
Dave McDonald Posted October 28, 2020 Report Share Posted October 28, 2020 Robin, They do rot. See photo of my TR5 nearside inner wheel arch. That patch was fitted during a 1993 restoration for the previous owner. I had no idea it was there until I stripped out the trim for my current restoration. It's not pretty but appears to be sound so I'm leaving it, but I have dressed the welds. It seems that water enters the bump stop "buttress" through not particularly sound factory welding and rots out from inside that box. I've had all the outer welds redone to prevent future water ingress and will drill a hole in the box so that I can seal it internally with Waxoyl and then seal the hole with a rubber bung.

stuart Posted October 29, 2020 Report Share Posted October 29, 2020 They do also fall off as Guy (Jersey Royal) can attest Stuart. Quote Link to post Share on other sites

RobinTR Posted October 30, 2020 Author Report Share Posted October 30, 2020 Dave, luckily no horrors on this part of my car... must be the only sound bit I have found! Visible corrosion was limited to some rust forcing one of the bottom plate tags away from the main bracket. As I am doing a "cut out all rust" restoration this tag was removed, revealing matching corrosion on the side of the bracket, so 15mm of this was trimmed away. This allowed me to look and feel around inside the bracket; I was very surprised to find only surface rust and no obvious thinning of the concave cap. Will consider drilling a drain hole at the lowest point of the bracket, which might also allow for future wax injection Quote Link to post Share on other sites
Mark69 Posted October 30, 2020 Report Share Posted October 30, 2020 Would it be worth drilling a hole from inside and spraying with dinatrol ml or the like. Quote Link to post Share on other sites
