Car Forum / Honda Cars / January 2007EG Civic Brake Master
Hi All, I think my Brake Master Cylinder is on its way out on my 1995 EG Honda Civic (1.5L D15B7) Recently with the hot weather after driving for a while I find that the pedal sinks to the ground which I believe to be cause by a faulty brake master cylinder. I have called up for some prices for a new part and i am up for around $370aud and I was wondering if I could save a few $$$ by rebuilding it. The Honda workshop manual has no instructions on how to do this and I was wondering weather it was worth trying to rebuild it or weather I just for for a new master cylinder. If anyone has instructions or can lead me to a place that has instructions on how to rebuild the unit it would be good. Also if I was to get a new master cylinder is it possible to fit a larger unit in from another car (Integra) to perhaps improve the feel of the brakes or should I just stick to the original specifications. Regards, Michael.

Don't you have jobbers in Australia? Surely you could pick up a reman from the jobber for a fraction of new OEM. Rebuilding is a good idea, provided you can get the parts and provided the bore isn't corroded. At least in North America, Honda does not sell MC parts to the public.  SignatureTegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ Ive never heard of "jobbers" here in Australia. I can get the pistons and seals from Honda for around $100 so I have put that down as an option. Aftermarket stuff is not the best sometimes thats why id rather stay genuine Honda or just rebuild it my self. > "MikeLikes" <MikeLikes@gmail.com> wrote in news:1168472755.613747.268590 > @o58g2000hsb.googlegroups.com: [quoted text clipped - 33 lines] > The Unofficial Honda/Acura FAQ > www.tegger.com/hondafaq/ >> Don't you have jobbers in Australia? >> [quoted text clipped - 6 lines] > > Ive never heard of "jobbers" here in Australia. Maybe you guys use a different term. "Jobber" in North America refers to places that sell aftermarket parts to garages and to the public. > I can get the pistons and seals from Honda for around $100 so I have > put that down as an option. If your bore is uncorroded, this would be the very best option other than a whole new MC. Just make 100% certain you exercise total cleanliness. No lint, no grit, no smears of grease. Not a trace. And you may have to adjust the MC pushrod under the dash afterwards, so be prepared for that. http://www.tegger.com/hondafaq/mastercylinderreplace/adjustment.html > Aftermarket stuff is not the best No kidding. It's usually shite. I took a flier and went with a NAPA-rebuilt MC for my Integra when mine wore out at 248,000 miles. I've noticed this one blackens the brake fluid faster than the OEM one did. I expect it to fail sooner than the original, and when it does, a brand-new OEM one is going in and hang the cost. > sometimes thats why id rather stay genuine Honda or just rebuild it my > self. Amen.

No lint, no grit, no smears of grease. Not a trace. But use new, clean brake fluid as a lubricant to help prevent damage to the seal lips. Do not try to assemble the parts dry.

Hm. Maybe it's just my Integra then. All I can buy is a new MC.

If anyone has instructions or can > lead me to a place that has instructions on how to rebuild the unit it > would be good. check tegger.com for a diagram. you'll need circlip pliers and silicone grease. remove the cylinder body, remove the rubber seal and guide to reveal the circlip. pressing the piston in about 3cm, remove the bolt you see on the side of the cylinder. that retains the primary piston. then remove the circlip. now, both pistons should come out. reassembly is reverse of removal. don't forget to use a little silicone on all the rubbers on assembly and to make sure the pistons are pushed in sufficiently before attempting to re-fit the retaining bolt. > Also if I was to get a new master cylinder is it possible to fit a > larger unit in from another car (Integra) to perhaps improve the feel > of the brakes or should I just stick to the original specifications. unless you're upgrading to big disks, i'd stick. it's all about the volume of the fluid pushed out each time you press the pedal. the usual piston diameters are 13/16, 7/8, 15/16, and 1". the bigger the diameter, the more fluid, shorter stroke, but also more pedal pressure. that can be helped by fitting the next size up servo, but if you're buying new, they're very expensive. junk yards are your friend. the 7/8 are relatively rare, but are found on some of the crx's. maybe del sols too. that might be ok. the 15/16 upgrade is biggest you can find to preserve existing pipe layout iirc. 1" requires pipe bending and really isn't a good idea without the disk upgrade. it's only fitted to abs models normally. usual upgrade is 15/16, [civic ex/del sol vtec?] big servo, with integra front & rear disks. don't forget the "4040" proportioning valve. |
