Mathew Posted March 16, 2021 Report Share Posted March 16, 2021 Is it posible to swap out a 2000/2500 servo without having to blead the brakes? As mine is still as heavy as the day i got it and my mk1 2000 was nice and light. Any things to watch out for if it is. Thinking of either repairing or swapping the servo to get some lighter breaking. Plus it niggles me . Link to comment Share on other sites More sharing options...
PeteH Posted March 16, 2021 Report Share Posted March 16, 2021 Hi You could try putting cling film over the top of the master cyl; reserviour, and put the cap back on?. Won`t stop a little fluid loss but will slow it right down. Cap the end of any pipework ASAP. Cannot off-hand think of any way to prevent having to bleed, Maybe if the fluid is 2 or more years old treat it as the oportunity to to completely renew the fluid?.

Pete Lewis Posted March 16, 2021 Report Share Posted March 16, 2021 you can de mount the M cyl away from the servo without disturbing any fluid two nuts and it off getting the clevis and 4 nuts down inside the fascia is a good game to get the servo off , leave the Mcyl just hanging on its pipe Pete 1 Link to comment Share on other sites More sharing options...
Mathew Posted March 16, 2021 Author Report Share Posted March 16, 2021 Thinking of a click and collect from rimmers today? Should i get one ready done or the repair kit? Thinking on easiest or best way rather than cost. Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 16, 2021 Report Share Posted March 16, 2021 cant say i fitted a new as the old one the plastic diaphragm piston fractured , its not the best feeling of brakes i have even fancied fitting a in the line remote extra servo the servo has to allow atmospheric pressure in via the cabin so there should be a foam filter that end of the servo make sure its clean Link to comment Share on other sites More sharing options...

Definitely vacuum on the pipe. No difference on brakes on or off. Its coming out. Link to comment Share on other sites More sharing options...
Mathew Posted March 16, 2021 Author Report Share Posted March 16, 2021 Not looking good for the master cylinder recon master cylinder? Did not expect wet this end? Came off with a bit of suction. Link to comment Share on other sites More sharing options...
Mathew Posted March 16, 2021 Author Report Share Posted March 16, 2021 With no assistance its hard to test the servo now! Could it be the master cylinder!? I remember on my mark 1 the brake pedal was softer after i changed the seals, they let go 70 miles from home, that was interesting. Then i just used a master cylinder repair kit. Could the seals in the master be at fault? I am lazy so anything that can save work. Link to comment Share on other sites More sharing options...
Mathew Posted March 16, 2021 Author Report Share Posted March 16, 2021 Ok, not scientific S W M B O came home after a walk. Holding pushrod, engine off with no vacuum. Felt pressure. With engine on smooth and alot easier? Worth putting attention to brakes/ master cylinder first as 200 pounds for the servo. Link to comment Share on other sites More sharing options...
Mathew Posted March 16, 2021 Author Report Share Posted March 16, 2021 Road trip to rimmers, seal kit for master cylinder first. Then up again if that does not work for the servo. If that dont work suggestions on a postcard. Link to comment Share on other sites More sharing options...
thescrapman Posted March 16, 2021 Report Share Posted March 16, 2021 Might be worth checking the seal on the cabin side is intact. probably a split in the diaphragm Link to comment Share on other sites More sharing options...

Not got this on the 2500s. Will try the new seal kit first, servo second and if thats no good the front brakes. On testing the vacuum on the pipe, open engine increased speed. On the servo speed back to normal idle, the master cylinder not on the servo. first thing tomorrow morning fit this kit on the master and blead. If no joy up to rimmers for a servo. Will check calipers when i blead them but as a hard press operates them and they don't stick on after i suspect they are ok. Link to comment Share on other sites More sharing options...
Mathew Posted March 17, 2021 Author Report Share Posted March 17, 2021 Stripdown One spare seal in kit? Worrying unless anyone knows if it should go anywhere its going back together as it came apart. Link to comment Share on other sites More sharing options...
Mathew Posted March 17, 2021 Author Report Share Posted March 17, 2021 All back together. Quick blead, not connected easy pedal, connected and air out hard pedal, then the engine on and i get more travel but still stiff. Taking a look at the caliper its past its best. Looks like a newish disk and green stuff pads. It has not been off the car for a long time. Rounded both bolts with the correct size 6 point socket! Me thinks these will need changing Link to comment Share on other sites More sharing options...

Pete Lewis Posted March 17, 2021 Report Share Posted March 17, 2021 not really , Garth got mine via rimmers when he was in the shop its a search , you will see what i mean about costs i also used a stag/TR7 rear shoe adjust/expander as it has same internal length but has 15mm extra on the short cable pivot lever gives a far better handbrake again available cheap and 2000 ones hens teeth £££s Pete Link to comment Share on other sites More sharing options...

Nick Jones Posted March 17, 2021 Report Share Posted March 17, 2021 Hateful Lockheed calipers with wholly inadequate weather sealing. Born to seize. Suggest Mintex M1144 pads if you actually want a bit of bite though. Nick Link to comment Share on other sites More sharing options...
thescrapman Posted March 17, 2021 Report Share Posted March 17, 2021 Never seen one rusted in that badly. looks like you sacrificed a few sockets as well. Link to comment Share on other sites More sharing options...
Mathew Posted March 17, 2021 Author Report Share Posted March 17, 2021 Sacrificed the day and a few old sockets. Fingers crossed for tomorrow, found a perished coolant hose with a couple of drips from it. Link to comment Share on other sites More sharing options...
PeteH Posted March 18, 2021 Report Share Posted March 18, 2021 The last time I had to remove a seized bolt like that, I welded a Larger Nut over the top of the bolt, that gives more purchase than the socket, the heat helps "crack" the corrosion, and saves expensive sockets. even old one`s.👍 Pete Link to comment Share on other sites More sharing options...
