1602 Brake mst cylinder

[Simeon]

This explains why it seems the obvious answer to me. It’s a fair point though, it is a specialised process where the body is machined to accept the sleeve to a close tolerance and the internal drilling’s are replicated. 

 

The remanufacturing process was devised in Australia where re-sleeving hydraulic cylinders is "the norm", Past Parts is one of the only companies in Europe with the equipment to provide this specialist service flew in specialist trainers from Australia to help setup the facility and train the engineering staff.

BEWARE refurbished units they are simply cleaned poorly with new rubber bits to make it look nice, yes BMW main dealer you included.

 

Pastparts is only place I use or recommend who refurbishes hydraulics properly is by drilling out and resleeving so it has smooth internal bore and much much longer life without leaks.

Thanks Shakeyc, have been in touch, £200 to refurbish both remote servos.

I was going to send my 1600-2 remote booster to a place here called Power Brake Exchange fora rebuild....but reading this thread makes me wonder how they rebuild them.  I looked into the place you are using....gah! is the tax really this high?

Hi Arminyack,

 

20% of 192 is approx 38.

 

231 minus 192 is 39, so about 20%.

 

Where did it state  83%?

 

what and where is imgur, in the UK?

 

cheers

Nothing to do with brake servos unfortunately. Photo sharing site.

I took the mst cylinder apart, and have ordered new seals etc. When I removed the plungers, the one furthest in was retained by a small screw which is inserted through the cylinder case and stops the spring from falling out.  I removed it in order to allow the spring to come out of the cylinder.

 

Can anyone tell me, when I replace the springs and insert this screw again, how this does not prevent the outer spring from pushing against the deeper spring?

 

cheers.

Ok update

 

removed brake mst cyl, what a joy?

 

Replaced seals with new ones rebuilt cyl, and replaced cyl on vehicle (double joy?).  Bled brakes again using a bleeder pump, still same issue, brake pedal goes all the way down to floor and very little pressure on brake (won't stop car).

 

Tearing hair out, pleas help me not go bald please.

 

any experts live in lincolnshire?

How is the brake plumbing split on these? Will unadjusted rears cause a low pedal?

1 set of pipes goes to the rear and the front, and another set go just to the front.

Unadjusted drums will cause a low pedal but doubt they would be bad enough to get to the floor.

 

what was the bore of the cylinder like when you rebuilt it. Any chance you could have a seal on backwards? You may just find that you have a lot of air trapped in the system. Did you bleed in the correct order, servos first followed by the left front caliper (inner, outer and then upper) and the right caliper before doing the rear brakes.  It might just take some effort to get all of the air out.
