| Lovely shiny new caliper!
Anyone else ever had a problem with tyre valves? Was getting a new tyre fitted and they could not find a valve big enough for the hole in the wheel. |  |

| I've just had this problem with a couple of Volvo Amazon wheels. Took a couple of repainted ones up to my tyre man for a chat and he tried some from his box but they were all too small. Bought half a dozen of the larger size from Midland Tyres on the web. Went back to get the tyres changed over and forund the old wheels had inner tubes. Not a problem but the wheels also had the large holes. Found that there was a small filler sleeve/grommet to space out and support the tube valve in the rim. Didn't have to use the large valves after all as we decided to keep with the tubes.
There are only 2 sizes "large" and "small" and a long established or used tyre place should know what you want. Might still have a few in a dusty box. My guy said he would have to buy a box of 100. Buying on line wasn't cheap at about £20 inc P&P for 6 but they were on my mat the next day after ringing them late afternoon. Good service. | |

| It's been awhile since I last worked on brakes, so thought I'd consult the Oracle (Saab-V4 co uk) and came across this thread.
I've acquired a pair of used calipers and plan to get them blasted and painted - but before I do, do the 'shoulders' look OK to you (ie: not worn, as mentioned in this thread)? They look OK to me, but thought I'd seek a second opinion...

| Look ok to me Simon, cannot see any edge wear where the pads will seat. Easily noticeable.
Did a set last year for the Troll, just using wire wheels. Blasting would have been better.
The Troll’s were done 35yrs ago, blasted and painted. Looking jaded now.
I can send photos which show where repairs have been done in the past.
Can’t host here yet.
Just ensure that the top hats at fixed post are clear and free moving and not too much wear in the slider at fixed pin. | |

| | Is the top hat - the spring at the top - how does that come apart (to clean it etc.)? | |

| | Yes, the top hats are inside the spring at fixed post, which get clogged with dust. | |

| | I take it there's no way to take that apart - just go at it with a wire brush (cheek poker) on a drill? | |

| Yes soak well and use wire brush by hand or drill.
I have seen repair kits used where post has been loose but the components have not been of good quality. I think it was on here sometime back.
You should be safe sand blasting it. | |

I replaced the "Top Hat" pin with stainless steel nuts and bolts, including a "locking" nut, and used loctite on the threads. Wouldn't want that assembly coming apart!!! Yikes!
I'll see if I can a get a photo. I've got the wings off at the moment. Might be possible.

Ah, you found my old thread from the summer of 2020. Who could forget that summer, eh? 6 weeks of wall to wall sunshine here in east central Scotland, and could not move more than 5 miles from the house.
That's why I stripped the whole back end out of the car that summer. No car shows to go to, nowt to do but sit in the sun and fizz!!!! So to the garage!!
That S/S bolt, and nut system on the calliper is still there. No issues.
