#1 Series 1.5 2+2 handbrake issues

Post by Freoway » Thu Aug 24, 2023 7:01 am

Hi, I realise that there are a few posts on this subject already, but I couldn't find my answer. I have a '68 S1.5 2+2 manual. I've had the IRS out whilst the body was being painted. The IRS was also apart, reco'd calipers fitted, etc., so there is a chance that I haven't hooked up the handbrake properly.

When I pull the handbrake, there is plenty of travel. I can see the mechanism levers move. The LH rear wheel binds, suggesting that the handbrake is working on that side. However, the RH rear wheel doesn't lock. Not sure why. Both sets of pads were replaced along with the main caliper pads. Is it likely that there is too much clearance on the RH side? Or is it possible that I haven't hooked things up properly.

Even with the two inspection panels removed (behind the rear seat), I can only see part of the handbrake mechanism. Is it more accessible from underneath? I can see the mechanism from underneath and adjust the cable tension, but I cannot get to the handbrake pads on each side.

Do I need to drop the IRS (again!)?

Thanks in advance, Lloyd

Hi Lloyd....each handbrake caliper has its own self adjusting ratchet mechanism....and a long bolt through it that you set up when refitting the calipers...however if the ratchet is working correctly then as you pull in the main handbrake the ratchet in the caliper should click and take up slack...listen for it...keep operating handbrake till the clicking stops....full details in service manual..Steve.....ps working on the handbrake is very difficult with the irs in the car...just changeing pads needs the irs out

Thanks. I've just realised that I can see what's happening from the rear of the car through the IRS. It appears as if the pin on one of the handbrake calipers has popped out. Not sure if it's possible to get one in without dropping the IRS (and the exhaust!). Bugger.
