Tech-guy Posted May 31, 2015 Report Share Posted May 31, 2015 I put Maxima rear disk brakes on my 510 but kept the 3/4 inch master cylinder. That combo had more pedal travel than I like. So, I went to 15/16 inch master cylinder. I like the pedal travel but the pedal effort is very high. I am thinking about adding a power brake booster. But there is not a lot of room, especially since the engine has dual Mikuni carbs. Does anyone have a suggestion as to which power brake booster would most likely fit? 1 Quote Link to comment
510freak Posted May 31, 2015 Report Share Posted May 31, 2015 You could get a 7/8 master cylinder A b210 booster will bolt in.(not sure if there are clearance issues with carbs) 2 Quote Link to comment
TENDRIL Posted May 31, 2015 Report Share Posted May 31, 2015 with a booster you will have an issue with filters/horns it can be done but you must use a short velocity stack with foam filters or go with a 13/16 out of a 310 i believe or a 7/8 1 Quote Link to comment
datzenmike Posted June 1, 2015 Report Share Posted June 1, 2015 Do you have a stock intake? Then a B-210 booster will work. 510s did come with a booster option so it will clear. 1 Quote Link to comment

datzenmike Posted June 1, 2015 Report Share Posted June 1, 2015 Poster has dual mikunis PL 510s? where was this a option? He should say so, it's critical for clearance. I'll look up the part numbers for it. Option I believe, so maybe uncommon. Maybe not in Canada, eh? Pitty. 1 Quote Link to comment

510freak Posted June 2, 2015 Report Share Posted June 2, 2015 I've seen coupes with the stock booster. That makes sense,but I dont think usa/canada ever got them? 1 Quote Link to comment
dscottdatsun Posted June 2, 2015 Report Share Posted June 2, 2015 That booster in the diagram looks a lot like the B210 booster and spacer. The B210 booster does fit and clears dual SU's. I can provide pic's if needed. 2 Quote Link to comment
510freak Posted June 2, 2015 Report Share Posted June 2, 2015 I have the b210 booster in my orange 510 fits great,but I am running a weber 32/36.had it there for 18 years, With dual mikunis,they will need the "high rise" cannon manifold(nicknamed the gooseneck) pic from the 510realm Robins gooseneck manifold 1 Quote Link to comment

I can see it being jdm market only,heck we had front drums on our 68s lol Manuals made alot of mistakes,info was over printed etc.. 1 Quote Link to comment
datzenmike Posted June 2, 2015 Report Share Posted June 2, 2015 I haven't see every 710 either. I can see one mistake but a page? It was an option no one wanted? My '68 had amber rear turn signals. 1 Quote Link to comment
510freak Posted June 2, 2015 Report Share Posted June 2, 2015 haha I have had my hands on many 510s. 68 510s here had amber turn signals,and b pillar interior light etc etc Show me a 510(not bluebird/coupe etc etc) from up here,with a factory booster? I dont think that will happen? 1 Quote Link to comment
uberkevin Posted June 2, 2015 Report Share Posted June 2, 2015 I think a member that goes by Tdaaj has a small brake booster he was trying to part with. 1 Quote Link to comment

But there is not a lot of room, especially since the engine has dual Mikuni carbs. Does anyone have a suggestion as to which power brake booster would most likely fit? You running front ZX struts/brakes also? You could forget the booster and get a 7/8" master from a 240Z-280Z. I have the ZX/ rear Maxima brakes on my 510 and recently replaced the ZX mc with a 7/8" mc from Troy Ermish. I'll tell you what!!! it works a whole lot better than the ZX mc with much better feel at the pedal. You could go out and buy the 7/8 MC but you need to replace the pressure valve behind the brake line in the MCfor the rear brakes with the valve from your ZX mc. It's a one beer job easy or just make the purchase from Ermish and simply bench bleed and install. But the push rod has to be shortened about 1/4" to get it in if you're using the ZX push rod. You could use the brake booster as that ZX MC was designed for a booster and not using one is why you're pedal is rock hard. 1 Quote Link to comment
