Gohn 62 Posted August 12, 2022 this topic was actually pilfered.. originally raised by Jay (good job !) while rambling sideways from the quaife rack "knocking" topic thought I'd better put up a separate topic as I've experienced a few clunks from the brakes I've got the TD Bendix setup mentioned by anthony they work ok, pad wear is even but get the occasional manouvering noise the knock is especially when reversing/rolling downhill and dabbing the brakes looked everywhere suspecting the wishbone bushes or engine mounts or balljoints etc etc but everything was good so was at a loss until saw the above unrelated topic luckily I have a set of the Girling GTi calipers that came on the car, but were removed and set aside for the TD Bendix setup only have used the base model Bendix and TD Bendix setups previously now considering refurbing the Girling GTi calipers and sticking them on will it be worth the effort, are they gunna be much better ? thanks all Share this post Link to post Share on other sites

Yes, far better IMO - just ensure that the sliders are in good condition and greased. If it's a TD, you're presumably running base model hubs and 1.9 GTi disks, correct? If so, you might find caliper clearance issues with some wheels, so check that before going too far - I know that the non-Speedline made 1.6 GTi alloys typically foul for example.

SRDT 144 Posted August 12, 2022 You can grind the calipers a bit to clear 1.6 wheels, there is not much material to remove: Share this post Link to post Share on other sites

Basically, yes, remembering that the sliders being retracted into the carrier brings the caliper closer to the wheel spokes and is how it'll be with new pads/disks. If I recall the STDT/Gentry wheels are OK clearance wise, but always worth double checking anyway with a spin of the wheel through at least a full revolution. It's also worth remembering that just because one wheel fits, doesn't necessarily mean that the other will (e,g, Speedline vs non-Speedline 1.6 GTi alloy, or differing placement of wheel weights on 1.9 GTi wheels when running GTi-6 calipers).

Ozymandis 96 Posted August 13, 2022 What pisses me off , every picture You post of old second hand bits, everythings not one big scab of rust like all ours are, dream condition rear axles, actual metal brake calipers, re-useable bolts, its not fair. Share this post Link to post Share on other sites
Gohn 62 Posted August 13, 2022 yeah its a bit of a blessing for sure you're all pretty good at coping with the salt, I'd struggle 13 hours ago, Anthony said: remembering that the sliders being retracted into the carrier brings the caliper closer to the wheel spokes and is how it'll be with new pads/disks. cheers A, would have missed that thanks for marking where to grind Baptiste, hopefully the gentry rims wont need though ready for test fit but may need to work around car use, it's only transport after all Share this post Link to post Share on other sites
Gohn 62 Posted September 30, 2022 updateroo cleaned up my girling calipers new pads new disks (although could still use the old ones if needed) got the caliper refurb kit today with piston oring, dustcover, and slider seals (didn't get new sliders though) now I've inserted the new cylinder seal, lubricated it and the piston with brake fluid but cannot get the piston down into the cylinder past the new oring seal the book says to just insert twisting as necessary but its not working at all what am I doing wrong ? is there some trick or technique to slot it in ? many thanks in advance Share this post Link to post Share on other sites
Gohn 62 Posted September 30, 2022 also, followed anthony's advice above and checked clearance for the Gentry/STDT rims while waiting for the caliper refurb kit and they have plenty of clearance for the 1.9GTi calipers so good to go on now managed to get the pistons back in the brake cylinders (there was a little corrosion on the top section of the cylinder bore above the oring) it was causing the close fit of the piston to just jam , some 1000grit was enough to unjam it also took out the bleed nipple to lessen any pressure resistance when putting the piston in Share this post Link to post Share on other sites
Gohn 62 Posted October 15, 2022 I've run the new brakes for about a thousand k's now and all my brake knocking has disappeared just quiet solid braking, very good and pleased thanks all for recommendations and pointers ! 1 Share this post Link to post Share on other sites
